+Release 2018e - 2018-05-01 23:42:51 -0700
+
+ Briefly:
+
+ North Korea switches back to +09 on 2018-05-05.
+ The main format uses negative DST again, for Ireland etc.
+ 'make tarballs' now also builds a rearguard tarball.
+ New 's' and 'd' suffixes in SAVE columns of Rule and Zone lines.
+
+ Changes to past and future time stamps
+
+ North Korea switches back from +0830 to +09 on 2018-05-05.
+ (Thanks to Kang Seonghoon, Arthur David Olson, Seo Sanghyeon,
+ and Tim Parenti.)
+
+ Bring back the negative-DST changes of 2018a, except be more
+ compatible with data parsers that do not support negative DST.
+ Also, this now affects historical time stamps in Namibia and the
+ former Czechoslovakia, not just Ireland. The main format now uses
+ negative DST to model time stamps in Europe/Dublin (from 1971 on),
+ Europe/Prague (1946/7), and Africa/Windhoek (1994/2017). This
+ does not affect UT offsets, only time zone abbreviations and the
+ tm_isdst flag. Also, this does not affect rearguard or vanguard
+ formats; effectively the main format now uses vanguard instead of
+ rearguard format. Data parsers that do not support negative DST
+ can still use data from the rearguard tarball described below.
+
+ Changes to build procedure
+
+ The command 'make tarballs' now also builds the tarball
+ tzdataVERSION-rearguard.tar.gz, which is like tzdataVERSION.tar.gz
+ except that it uses rearguard format intended for trailing-edge
+ data parsers.
+
+ Changes to data format and to code
+
+ The SAVE column of Rule and Zone lines can now have an 's' or 'd'
+ suffix, which specifies whether the adjusted time is standard time
+ or daylight saving time. If no suffix is given, daylight saving
+ time is used if and only if the SAVE column is nonzero; this is
+ the longstanding behavior. Although this new feature is not used
+ in tzdata, it could be used to specify the legal time in Namibia
+ 1994-2017, as opposed to the popular time (see below).
+
+ Changes to past time stamps
+
+ From 1994 through 2017 Namibia observed DST in winter, not summer.
+ That is, it used negative DST, as Ireland still does. This change
+ does not affect UTC offsets; it affects only the tm_isdst flag and
+ the abbreviation used during summer, which is now CAT, not WAST.
+ Although (as noted by Michael Deckers) summer and winter time were
+ both simply called "standard time" in Namibian law, in common
+ practice winter time was considered to be DST (as noted by Stephen
+ Colebourne). The full effect of this change is only in vanguard
+ format; in rearguard and main format, the tm_isdst flag is still
+ zero in winter and nonzero in summer.
+
+ In 1946/7 Czechoslovakia also observed negative DST in winter.
+ The full effect of this change is only in vanguard format; in
+ rearguard and main formats, it is modeled as plain GMT without
+ daylight saving. Also, the dates of some 1944/5 DST transitions
+ in Czechoslovakia have been changed.
+
+
+Release 2018d - 2018-03-22 07:05:46 -0700
+
+ Briefly:
+
+ Palestine starts DST a week earlier in 2018.
+ Add support for vanguard and rearguard data consumers.
+ Add subsecond precision to source data format, though not to data.
+
+ Changes to future time stamps
+
+ In 2018, Palestine starts DST on March 24, not March 31.
+ Adjust future predictions accordingly. (Thanks to Sharef Mustafa.)
+
+ Changes to past and future time stamps
+
+ Casey Station in Antarctica changed from +11 to +08 on 2018-03-11
+ at 04:00. (Thanks to Steffen Thorsen.)
+
+ Changes to past time stamps
+
+ Historical transitions for Uruguay, represented by
+ America/Montevideo, have been updated per official legal documents,
+ replacing previous data mainly originating from the inventions of
+ Shanks & Pottenger. This has resulted in adjustments ranging from
+ 30 to 90 minutes in either direction over at least two dozen
+ distinct periods ranging from one day to several years in length.
+ A mere handful of pre-1991 transitions are unaffected; data since
+ then has come from more reliable contemporaneous reporting. These
+ changes affect various timestamps in 1920-1923, 1936, 1939,
+ 1942-1943, 1959, 1966-1970, 1972, 1974-1980, and 1988-1990.
+ Additionally, Uruguay's pre-standard-time UT offset has been
+ adjusted westward by 7 seconds, from UT-03:44:44 to UT-03:44:51, to
+ match the location of the Observatory of the National Meteorological
+ Institute in Montevideo.
+ (Thanks to Jeremie Bonjour, Tim Parenti, and Michael Deckers.)
+
+ Enderbury and Kiritimati skipped New Year's Eve 1994, not
+ New Year's Day 1995. (Thanks to Kerry Shetline.)
+
+ Fix the 1912-01-01 transition for Portugal and its colonies.
+ This transition was at 00:00 according to the new UT offset, not
+ according to the old one. Also assume that Cape Verde switched on
+ the same date as the rest, not in 1907. This affects
+ Africa/Bissau, Africa/Sao_Tome, Asia/Macau, Atlantic/Azores,
+ Atlantic/Cape_Verde, Atlantic/Madeira, and Europe/Lisbon.
+ (Thanks to Michael Deckers.)
+
+ Fix an off-by-1 error for pre-1913 timestamps in Jamaica and in
+ Turks & Caicos.
+
+ Changes to past time zone abbreviations
+
+ MMT took effect in Uruguay from 1908-06-10, not 1898-06-28. There
+ is no clock change associated with the transition.
+
+ Changes to build procedure
+
+ The new DATAFORM macro in the Makefile lets the installer choose
+ among three source data formats. The idea is to lessen downstream
+ disruption when data formats are improved.
+
+ * DATAFORM=vanguard installs from the latest, bleeding-edge
+ format. DATAFORM=main (the default) installs from the format
+ used in the 'africa' etc. files. DATAFORM=rearguard installs
+ from a trailing-edge format. Eventually, elements of today's
+ vanguard format should move to the main format, and similarly
+ the main format's features should eventually move to the
+ rearguard format.
+
+ * In the current version, the main and rearguard formats are
+ identical and match that of 2018c, so this change does not
+ affect default behavior. The vanguard format currently contains
+ one feature not in the main format: negative SAVE values. This
+ improves support for Ireland, which uses Irish Standard Time
+ (IST, UTC+01) in summer and GMT (UTC) in winter. tzcode has
+ supported negative SAVE values for decades, and this feature
+ should move to the main format soon. However, it will not move
+ to the rearguard format for quite some time because some
+ downstream parsers do not support it.
+
+ * The build procedure constructs three files vanguard.zi, main.zi,
+ and rearguard.zi, one for each format. The files represent the
+ same data as closely as the formats allow. These three files
+ are intended for downstream data consumers and are not
+ installed. Zoneinfo parsers that do not support negative SAVE values
+ should start using rearguard.zi, so that they will be unaffected
+ when the negative-DST feature moves from vanguard to main.
+ Bleeding-edge Zoneinfo parsers that support the new features
+ already can use vanguard.zi; in this respect, current tzcode is
+ bleeding-edge.
+
+ The Makefile should now be safe for parallelized builds, and 'make
+ -j to2050new.tzs' is now much faster on a multiprocessor host
+ with GNU Make.
+
+ When built with -DSUPPRESS_TZDIR, the tzcode library no longer
+ prepends TZDIR/ to file names that do not begin with '/'. This is
+ not recommended for general use, due to its security implications.
+ (From a suggestion by Manuela Friedrich.)
+
+ Changes to code
+
+ zic now accepts subsecond precision in expressions like
+ 00:19:32.13, which is approximately the legal time of the
+ Netherlands from 1835 to 1937. However, because it is
+ questionable whether the few recorded uses of non-integer offsets
+ had subsecond precision in practice, there are no plans for tzdata
+ to use this feature. (Thanks to Steve Allen for pointing out
+ the limitations of historical data in this area.)
+
+ The code is a bit more portable to MS-Windows. Installers can
+ compile with -DRESERVE_STD_EXT_IDS on MS-Windows platforms that
+ reserve identifiers like 'localtime'. (Thanks to Manuela
+ Friedrich).
+
+ Changes to documentation and commentary
+
+ theory.html now outlines tzdb's extensions to POSIX's model for
+ civil time, and has a section "POSIX features no longer needed"
+ that lists POSIX API components that are now vestigial.
+ (From suggestions by Steve Summit.) It also better distinguishes
+ time zones from tz regions. (From a suggestion by Guy Harris.)
+
+ Commentary is now more consistent about using the phrase "daylight
+ saving time", to match the C name tm_isdst. Daylight saving time
+ need not occur in summer, and need not have a positive offset from
+ standard time.
+
+ Commentary about historical transitions in Uruguay has been expanded
+ with links to many relevant legal documents.
+ (Thanks to Tim Parenti.)
+
+ Commentary now uses some non-ASCII characters with Unicode value
+ less than U+0100, as they can be useful and should work even with
+ older editors such as XEmacs.
+
+
+Release 2018c - 2018-01-22 23:00:44 -0800
+
+ Briefly:
+ Revert Irish changes that relied on negative SAVE values.
+
+ Changes to tm_isdst
+
+ Revert the 2018a change to Europe/Dublin. As before, this change
+ does not affect UT offsets or abbreviations; it affects only
+ whether timestamps are considered to be standard time or
+ daylight-saving time, as expressed in the tm_isdst flag of C's
+ struct tm type. This reversion is intended to be a temporary
+ workaround for problems discovered with downstream uses of
+ releases 2018a and 2018b, which implemented Irish time by using
+ negative SAVE values in the Eire rules of the 'europe' file.
+ Although negative SAVE values have been part of tzcode for many
+ years and are supported by many platforms, they were not
+ documented before 2018a and ICU and OpenJDK do not currently
+ support them. A mechanism to export data to platforms lacking
+ support for negative DST is planned to be developed before the
+ change is reapplied. (Problems reported by Deborah Goldsmith and
+ Stephen Colebourne.)
+
+ Changes to past time stamps
+
+ Japanese DST transitions (1948-1951) were Sundays at 00:00, not
+ Saturdays or Sundays at 02:00. (Thanks to Takayuki Nikai.)
+
+ Changes to build procedure
+
+ The build procedure now works around mawk 1.3.3's lack of support
+ for character class expressions. (Problem reported by Ohyama.)
+
+
+Release 2018b - 2018-01-17 23:24:48 -0800
+
+ Briefly:
+ Fix a packaging problem in tz2018a, which was missing 'pacificnew'.
+
+ Changes to build procedure
+
+ The distribution now contains the file 'pacificnew' again.
+ This file was inadvertantly omitted in the 2018a distribution.
+ (Problem reported by Matias Fonzo.)
+
+
+Release 2018a - 2018-01-12 22:29:21 -0800
+
+ Briefly:
+ São Tomé and Príncipe switched from +00 to +01.
+ Brazil's DST will now start on November's first Sunday.
+ Ireland's standard time is now in the summer, not the winter.
+ Use Debian-style installation locations, instead of 4.3BSD-style.
+ New zic option -t.
+
+ Changes to past and future time stamps
+
+ São Tomé and Príncipe switched from +00 to +01 on 2018-01-01 at
+ 01:00. (Thanks to Steffen Thorsen and Michael Deckers.)
+
+ Changes to future time stamps
+
+ Starting in 2018 southern Brazil will begin DST on November's
+ first Sunday instead of October's third Sunday. (Thanks to
+ Steffen Thorsen.)
+
+ Changes to past time stamps
+
+ A discrepancy of 4 s in timestamps before 1931 in South Sudan has
+ been corrected. The 'backzone' and 'zone.tab' files did not agree
+ with the 'africa' and 'zone1970.tab' files. (Problem reported by
+ Michael Deckers.)
+
+ The abbreviation invented for Bolivia Summer Time (1931-2) is now
+ BST instead of BOST, to be more consistent with the convention
+ used for Latvian Summer Time (1918-9) and for British Summer Time.
+
+ Changes to tm_isdst
+
+ Change Europe/Dublin so that it observes Irish Standard Time (UT
+ +01) in summer and GMT (as negative daylight-saving) in winter,
+ instead of observing standard time (GMT) in winter and Irish
+ Summer Time (UT +01) in summer. This change does not affect UT
+ offsets or abbreviations; it affects only whether timestamps are
+ considered to be standard time or daylight-saving time, as
+ expressed in the tm_isdst flag of C's struct tm type.
+ (Discrepancy noted by Derick Rethans.)
+
+ Changes to build procedure
+
+ The default installation locations have been changed to mostly
+ match Debian circa 2017, instead of being designed as an add-on to
+ 4.3BSD circa 1986. This affects the Makefile macros TOPDIR,
+ TZDIR, MANDIR, and LIBDIR. New Makefile macros TZDEFAULT, USRDIR,
+ USRSHAREDIR, BINDIR, ZDUMPDIR, and ZICDIR let installers tailor
+ locations more precisely. (This responds to suggestions from
+ Brian Inglis and from Steve Summit.)
+
+ The default installation procedure no longer creates the
+ backward-compatibility link US/Pacific-New, which causes
+ confusion during user setup (e.g., see Debian bug 815200).
+ Use 'make BACKWARD="backward pacificnew"' to create the link
+ anyway, for now. Eventually we plan to remove the link entirely.
+
+ tzdata.zi now contains a version-number comment.
+ (Suggested by Tom Lane.)
+
+ The Makefile now quotes values like BACKWARD more carefully when
+ passing them to the shell. (Problem reported by Zefram.)
+
+ Builders no longer need to specify -DHAVE_SNPRINTF on platforms
+ that have snprintf and use pre-C99 compilers. (Problem reported
+ by Jon Skeet.)
+
+ Changes to code
+
+ zic has a new option -t FILE that specifies the location of the
+ file that determines local time when TZ is unset. The default for
+ this location can be configured via the new TZDEFAULT makefile
+ macro, which defaults to /etc/localtime.
+
+ Diagnostics and commentary now distinguish UT from UTC more
+ carefully; see theory.html for more information about UT vs UTC.
+
+ zic has been ported to GCC 8's -Wstringop-truncation option.
+ (Problem reported by Martin Sebor.)
+
+ Changes to documentation and commentary
+
+ The zic man page now documents the longstanding behavior that
+ times and years can be out of the usual range, with negative times
+ counting backwards from midnight and with year 0 preceding year 1.
+ (Problem reported by Michael Deckers.)
+
+ The theory.html file now mentions the POSIX limit of six chars
+ per abbreviation, and lists alphabetic abbreviations used.
+
+ The files tz-art.htm and tz-link.htm have been renamed to
+ tz-art.html and tz-link.html, respectively, for consistency with
+ other file names and to simplify web server configuration.
+
+
+Release 2017c - 2017-10-20 14:49:34 -0700
+
+ Briefly:
+ Northern Cyprus switches from +03 to +02/+03 on 2017-10-29.
+ Fiji ends DST 2018-01-14, not 2018-01-21.
+ Namibia switches from +01/+02 to +02 on 2018-04-01.
+ Sudan switches from +03 to +02 on 2017-11-01.
+ Tonga likely switches from +13/+14 to +13 on 2017-11-05.
+ Turks & Caicos switches from -04 to -05/-04 on 2018-11-04.
+ A new file tzdata.zi now holds a small text copy of all data.
+ The zic input format has been regularized slightly.
+
+ Changes to future time stamps
+
+ Northern Cyprus has decided to resume EU rules starting
+ 2017-10-29, thus reinstituting winter time.
+
+ Fiji ends DST 2018-01-14 instead of the 2018-01-21 previously
+ predicted. (Thanks to Dominic Fok.) Adjust future predictions
+ accordingly.
+
+ Namibia will switch from +01 with DST to +02 all year on
+ 2017-09-03 at 02:00. This affects UT offsets starting 2018-04-01
+ at 02:00. (Thanks to Steffen Thorsen.)
+
+ Sudan will switch from +03 to +02 on 2017-11-01. (Thanks to Ahmed
+ Atyya and Yahia Abdalla.) South Sudan is not switching, so
+ Africa/Juba is no longer a link to Africa/Khartoum.
+
+ Tonga has likely ended its experiment with DST, and will not
+ adjust its clocks on 2017-11-05. Although Tonga has not announced
+ whether it will continue to observe DST, the IATA is assuming that
+ it will not. (Thanks to David Wade.)
+
+ Turks & Caicos will switch from -04 all year to -05 with US DST on
+ 2018-03-11 at 03:00. This affects UT offsets starting 2018-11-04
+ at 02:00. (Thanks to Steffen Thorsen.)
+
+ Changes to past time stamps
+
+ Namibia switched from +02 to +01 on 1994-03-21, not 1994-04-03.
+ (Thanks to Arthur David Olson.)
+
+ Detroit did not observe DST in 1967.
+
+ Use railway time for Asia/Kolkata before 1941, by switching to
+ Madras local time (UT +052110) in 1870, then to IST (UT +0530) in
+ 1906. Also, treat 1941-2's +0630 as DST, like 1942-5.
+
+ Europe/Dublin's 1946 and 1947 fallback transitions occurred at
+ 02:00 standard time, not 02:00 DST. (Thanks to Michael Deckers.)
+
+ Pacific/Apia and Pacific/Pago_Pago switched from Antipodean to
+ American time in 1892, not 1879. (Thanks to Michael Deckers.)
+
+ Adjust the 1867 transition in Alaska to better reflect the
+ historical record, by changing it to occur on 1867-10-18 at 15:30
+ Sitka time rather than at the start of 1867-10-17 local time.
+ Although strictly speaking this is accurate only for Sitka,
+ the rest of Alaska's blanks need to be filled in somehow.
+
+ Fix off-by-one errors in UT offsets for Adak and Nome before 1867.
+ (Thanks to Michael Deckers.)
+
+ Add 7 s to the UT offset in Asia/Yangon before 1920.
+
+ Changes to zone names
+
+ Remove Canada/East-Saskatchewan from the 'backward' file, as it
+ exceeded the 14-character limit and was an unused misnomer anyway.
+
+ Changes to build procedure
+
+ To support applications that prefer to read time zone data in text
+ form, two zic input files tzdata.zi and leapseconds are now
+ installed by default. The commands 'zic tzdata.zi' and 'zic -L
+ leapseconds tzdata.zi' can reproduce the tzdata binary files
+ without and with leap seconds, respectively. To prevent these two
+ new files from being installed, use 'make TZDATA_TEXT=', and to
+ suppress leap seconds from the tzdata text installation, use 'make
+ TZDATA_TEXT=tzdata.zi'.
+
+ 'make BACKWARD=' now suppresses backward-compatibility names
+ like 'US/Pacific' that are defined in the 'backward' and
+ 'pacificnew' files.
+
+ 'make check' now works on systems that lack a UTF-8 locale,
+ or that lack the nsgmls program. Set UTF8_LOCALE to configure
+ the name of a UTF-8 locale, if you have one.
+
+ Y2K runtime checks are no longer enabled by default. Add
+ -DDEPRECATE_TWO_DIGIT_YEARS to CFLAGS to enable them, instead of
+ adding -DNO_RUN_TIME_WARNINGS_ABOUT_YEAR_2000_PROBLEMS_THANK_YOU
+ to disable them. (New name suggested by Brian Inglis.)
+
+ The build procedure for zdump now works on AIX 7.1.
+ (Problem reported by Kees Dekker.)
+
+ Changes to code
+
+ zic and the reference runtime now reject multiple leap seconds
+ within 28 days of each other, or leap seconds before the Epoch.
+ As a result, support for double leap seconds, which was
+ obsolescent and undocumented, has been removed. Double leap
+ seconds were an error in the C89 standard; they have never existed
+ in civil timekeeping. (Thanks to Robert Elz and Bradley White for
+ noticing glitches in the code that uncovered this problem.)
+
+ zic now warns about use of the obsolescent and undocumented -y
+ option, and about use of the obsolescent TYPE field of Rule lines.
+
+ zic now allows unambiguous abbreviations like "Sa" and "Su" for
+ weekdays; formerly it rejected them due to a bug. Conversely, zic
+ no longer considers non-prefixes to be abbreviations; for example,
+ it no longer accepts "lF" as an abbreviation for "lastFriday".
+ Also, zic warns about the undocumented usage with a "last-"
+ prefix, e.g., "last-Fri".
+
+ Similarly, zic now accepts the unambiguous abbreviation "L" for
+ "Link" in ordinary context and for "Leap" in leap-second context.
+ Conversely, zic no longer accepts non-prefixes such as "La" as
+ abbreviations for words like "Leap".
+
+ zic no longer accepts leap second lines in ordinary input, or
+ ordinary lines in leap second input. Formerly, zic sometimes
+ warned about this undocumented usage and handled it incorrectly.
+
+ The new macro HAVE_TZNAME governs whether the tzname external
+ variable is exported, instead of USG_COMPAT. USG_COMPAT now
+ governs only the external variables "timezone" and "daylight".
+ This change is needed because the three variables are not in the
+ same category: although POSIX requires tzname, it specifies the
+ other two variables as optional. Also, USG_COMPAT is now 1 or 0:
+ if not defined, the code attempts to guess it from other macros.
+
+ localtime.c and difftime.c no longer require stdio.h, and .c files
+ other than zic.c no longer require sys/wait.h.
+
+ zdump.c no longer assumes snprintf. (Reported by Jonathan Leffler.)
+
+ Calculation of time_t extrema works around a bug in GCC 4.8.4
+ (Reported by Stan Shebs and Joseph Myers.)
+
+ zic.c no longer mistranslates formats of line numbers in non-English
+ locales. (Problem reported by Benno Schulenberg.)

+Release 2017b - 2017-03-17 07:30:38 -0700
+
+ Briefly: Haiti has resumed DST.
+
+ Changes to past and future time stamps
+
+ Haiti resumed observance of DST in 2017. (Thanks to Steffen Thorsen.)
+
+ Changes to past time stamps
+
+ Liberia changed from -004430 to +00 on 1972-01-07, not 1972-05-01.
+
+ Use "MMT" to abbreviate Liberia's time zone before 1972, as "-004430"
+ is one byte over the POSIX limit. (Problem reported by Derick Rethans.)
+
+ Changes to code
+
+ The reference localtime implementation now falls back on the
+ current US daylight-saving transition rules rather than the
+ 1987-2006 rules. This fallback occurs only when (1) the TZ
+ environment variable's value has a name like "AST4ADT" that asks
+ for daylight saving time but does not specify the rules, (2) there
+ is no file by that name, and (3) the TZDEFRULES file cannot be
+ loaded. (Thanks to Tom Lane.)
+
+
+Release 2017a - 2017-02-28 00:05:36 -0800
+
+ Briefly: Southern Chile moves from -04/-03 to -03, and Mongolia
+ discontinues DST.
+
+ Changes to future time stamps
+
+ Mongolia no longer observes DST. (Thanks to Ganbold Tsagaankhuu.)
+
+ Chile's Region of Magallanes moves from -04/-03 to -03 year-round.
+ Its clocks diverge from America/Santiago starting 2017-05-13 at
+ 23:00, hiving off a new zone America/Punta_Arenas. Although the
+ Chilean government says this change expires in May 2019, for now
+ assume it's permanent. (Thanks to Juan Correa and Deborah
+ Goldsmith.) This also affects Antarctica/Palmer.
+
+ Changes to past time stamps
+
+ Fix many entries for historical time stamps for Europe/Madrid
+ before 1979, to agree with tables compiled by Pere Planesas of the
+ National Astronomical Observatory of Spain. As a side effect,
+ this changes some time stamps for Africa/Ceuta before 1929, which
+ are probably guesswork anyway. (Thanks to Steve Allen and
+ Pierpaolo Bernardi for the heads-ups, and to Michael Deckers for
+ correcting the 1901 transition.)
+
+ Ecuador observed DST from 1992-11-28 to 1993-02-05.
+ (Thanks to Alois Treindl.)
+
+ Asia/Atyrau and Asia/Oral were at +03 (not +04) before 1930-06-21.
+ (Thanks to Stepan Golosunov.)
+
+ Changes to past and future time zone abbreviations
+
+ Switch to numeric time zone abbreviations for South America, as
+ part of the ongoing project of removing invented abbreviations.
+ This avoids the need to invent an abbreviation for the new Chilean
+ new zone. Similarly, switch from invented to numeric time zone
+ abbreviations for Afghanistan, American Samoa, the Azores,
+ Bangladesh, Bhutan, the British Indian Ocean Territory, Brunei,
+ Cape Verde, Chatham Is, Christmas I, Cocos (Keeling) Is, Cook Is,
+ Dubai, East Timor, Eucla, Fiji, French Polynesia, Greenland,

+ Pierre & Miquelon, Samoa, Saudi Arabia, Seychelles, Singapore,
+ Solomon Is, Tokelau, Tuvalu, Wake, Vanuatu, Wallis & Futuna, and
+ Xinjiang; for 20-minute daylight saving time in Ghana before 1943;
+ for half-hour daylight saving time in Belize before 1944 and in
+ the Dominican Republic before 1975; and for Canary Islands before
+ 1946, for Guinea-Bissau before 1975, for Iceland before 1969, for
+ Indian Summer Time before 1942, for Indonesia before around 1964,
+ for Kenya before 1960, for Liberia before 1973, for Madeira before

+ Pakistan before 1971, for Western Sahara before 1977, and for
+ Zaporozhye in 1880-1924.
+
+ For Alaska time from 1900 through 1967, instead of "CAT" use the
+ abbreviation "AST", the abbreviation commonly used at the time
+ (Atlantic Standard Time had not been standardized yet). Use "AWT"
+ and "APT" instead of the invented abbreviations "CAWT" and "CAPT".
+
+ Use "CST" and "CDT" instead of invented abbreviations for Macau
+ before 1999 and Taiwan before 1938, and use "JST" instead of the
+ invented abbreviation "JCST" for Japan and Korea before 1938.
+
+ Change to database entry category
+
+ Move the Pacific/Johnston link from 'australasia' to 'backward',
+ since Johnston is now uninhabited.
+
+ Changes to code
+
+ zic no longer mishandles some transitions in January 2038 when it
+ attempts to work around Qt bug 53071. This fixes a bug affecting
+ Pacific/Tongatapu that was introduced in zic 2016e. localtime.c
+ now contains a workaround, useful when loading a file generated by
+ a buggy zic. (Problem and localtime.c fix reported by Bradley
+ White.)
+
+ zdump -i now outputs non-hour numeric time zone abbreviations
+ without a colon, e.g., "+0530" rather than "+05:30". This agrees
+ with zic %z and with common practice, and simplifies auditing of
+ zdump output.
+
+ zdump is now buildable again with -DUSE_LTZ=0.
+ (Problem reported by Joseph Myers.)
+
+ zdump.c now always includes private.h, to avoid code duplication
+ with private.h. (Problem reported by Kees Dekker.)
+
+ localtime.c no longer mishandles early or late timestamps
+ when TZ is set to a POSIX-style string that specifies DST.
+ (Problem reported by Kees Dekker.)
+
+ date and strftime now cause %z to generate "-0000" instead of
+ "+0000" when the UT offset is zero and the time zone abbreviation
+ begins with "-".
+
+ Changes to documentation and commentary
+
+ The 'Theory' file now better documents choice of historical time
+ zone abbreviations. (Problems reported by Michael Deckers.)
+
+ tz-link.htm now covers leap smearing, which is popular in clouds.

+
+Release 2016j - 2016-11-22 23:17:13 -0800
+

+
+ Changes to future time stamps
+
+ Saratov, Russia switches from +03 to +04 on 2016-12-04 at 02:00.
+ This hives off a new zone Europe/Saratov from Europe/Volgograd.
+ (Thanks to Yuri Konotopov and Stepan Golosunov.)
+
+ Changes to past time stamps
+
+ The new zone Asia/Atyrau for Atyraū Region, Kazakhstan, is like
+ Asia/Aqtau except it switched from +05/+06 to +04/+05 in spring
+ 1999, not fall 1994. (Thanks to Stepan Golosunov.)
+
+ Changes to past time zone abbreviations
+
+ Asia/Gaza and Asia/Hebron now use "EEST", not "EET", to denote
+ summer time before 1948. The old use of "EET" was a typo.
+
+ Changes to code
+
+ zic no longer mishandles file systems that lack hard links, fixing
+ bugs introduced in 2016g. (Problems reported by Tom Lane.)
+ Also, when the destination already contains symbolic links, zic
+ should now work better on systems where the 'link' system call
+ does not follow symbolic links.
+
+ Changes to documentation and commentary
+
+ tz-link.htm now documents the relationship between release version
+ numbers and development-repository commit tags. (Suggested by
+ Paul Koning.)
+
+ The 'Theory' file now documents UT.
+
+ iso3166.tab now accents "Curaçao", and commentary now mentions

+
+
+Release 2016i - 2016-11-01 23:19:52 -0700
+
+ Briefly: Cyprus split into two time zones on 2016-10-30, and Tonga
+ reintroduces DST on 2016-11-06.
+
+ Changes to future time stamps
+
+ Pacific/Tongatapu begins DST on 2016-11-06 at 02:00, ending on
+ 2017-01-15 at 03:00. Assume future observances in Tonga will be
+ from the first Sunday in November through the third Sunday in
+ January, like Fiji. (Thanks to Pulu ʻAnau.) Switch to numeric
+ time zone abbreviations for this zone.
+
+ Changes to past and future time stamps
+
+ Northern Cyprus is now +03 year round, causing a split in Cyprus
+ time zones starting 2016-10-30 at 04:00. This creates a zone
+ Asia/Famagusta. (Thanks to Even Scharning and Matt Johnson.)
+
+ Antarctica/Casey switched from +08 to +11 on 2016-10-22.
+ (Thanks to Steffen Thorsen.)
+
+ Changes to past time stamps
+
+ Several corrections were made for pre-1975 time stamps in Italy.
+ These affect Europe/Malta, Europe/Rome, Europe/San_Marino, and
+ Europe/Vatican.
+
+ First, the 1893-11-01 00:00 transition in Italy used the new UT
+ offset (+01), not the old (+00:49:56). (Thanks to Michael
+ Deckers.)
+
+ Second, rules for daylight saving in Italy were changed to agree
+ with Italy's National Institute of Metrological Research (INRiM)
+ except for 1944, as follows (thanks to Pierpaolo Bernardi, Brian
+ Inglis, and Michael Deckers):
+
+ The 1916-06-03 transition was at 24:00, not 00:00.
+
+ The 1916-10-01, 1919-10-05, and 1920-09-19 transitions were at
+ 00:00, not 01:00.
+
+ The 1917-09-30 and 1918-10-06 transitions were at 24:00, not
+ 01:00.
+
+ The 1944-09-17 transition was at 03:00, not 01:00. This
+ particular change is taken from Italian law as INRiM's table,
+ (which says 02:00) appears to have a typo here. Also, keep the
+ 1944-04-03 transition for Europe/Rome, as Rome was controlled by
+ Germany then.
+
+ The 1967-1970 and 1972-1974 fallback transitions were at 01:00,
+ not 00:00.
+
+ Changes to code
+
+ The code should now be buildable on AmigaOS merely by setting the
+ appropriate Makefile variables. (From a patch by Carsten Larsen.)
+
+
+Release 2016h - 2016-10-19 23:17:57 -0700
+
+ Changes to future time stamps
+
+ Asia/Gaza and Asia/Hebron end DST on 2016-10-29 at 01:00, not
+ 2016-10-21 at 00:00. (Thanks to Sharef Mustafa.) Predict that
+ future fall transitions will be on the last Saturday of October
+ at 01:00, which is consistent with predicted spring transitions
+ on the last Saturday of March. (Thanks to Tim Parenti.)
+
+ Changes to past time stamps
+
+ In Turkey, transitions in 1986-1990 were at 01:00 standard time
+ not at 02:00, and the spring 1994 transition was on March 20, not
+ March 27. (Thanks to Kıvanç Yazan.)
+
+ Changes to past and future time zone abbreviations
+
+ Asia/Colombo now uses numeric time zone abbreviations like "+0530"
+ instead of alphabetic ones like "IST" and "LKT". Various
+ English-language sources use "IST", "LKT" and "SLST", with no
+ working consensus. (Usage of "SLST" mentioned by Sadika
+ Sumanapala.)
+
+ Changes to code
+
+ zic no longer mishandles relativizing file names when creating
+ symbolic links like /etc/localtime, when these symbolic links
+ are outside the usual directory hierarchy. This fixes a bug
+ introduced in 2016g. (Problem reported by Andreas Stieger.)
+
+ Changes to build procedure
+
+ New rules 'traditional_tarballs' and 'traditional_signatures' for
+ building just the traditional-format distribution. (Requested by
+ Deborah Goldsmith.)
+
+ The file 'version' is now put into the tzdata tarball too.
+ (Requested by Howard Hinnant.)
+
+ Changes to documentation and commentary
+
+ The 'Theory' file now has a section on interface stability.
+ (Requested by Paul Koning.) It also mentions features like
+ tm_zone and localtime_rz that have long been supported by the
+ reference code.
+
+ tz-link.htm has improved coverage of time zone boundaries suitable
+ for geolocation. (Thanks to heads-ups from Evan Siroky and Matt
+ Johnson.)
+
+ The US commentary now mentions Allen and the "day of two noons".
+
+ The Fiji commentary mentions the government's 2016-10-03 press
+ release. (Thanks to Raymond Kumar.)
+
+
+Release 2016g - 2016-09-13 08:56:38 -0700
+
+ Changes to future time stamps
+
+ Turkey switched from EET/EEST (+02/+03) to permanent +03,
+ effective 2016-09-07. (Thanks to Burak AYDIN.) Use "+03" rather
+ than an invented abbreviation for the new time.
+
+ New leap second 2016-12-31 23:59:60 UTC as per IERS Bulletin C 52.
+ (Thanks to Tim Parenti.)
+
+ Changes to past time stamps
+
+ For America/Los_Angeles, spring-forward transition times have been
+ corrected from 02:00 to 02:01 in 1948, and from 02:00 to 01:00 in
+ 1950-1966.
+
+ For zones using Soviet time on 1919-07-01, transitions to UT-based
+ time were at 00:00 UT, not at 02:00 local time. The affected
+ zones are Europe/Kirov, Europe/Moscow, Europe/Samara, and
+ Europe/Ulyanovsk. (Thanks to Alexander Belopolsky.)
+
+ Changes to past and future time zone abbreviations
+
+ The Factory zone now uses the time zone abbreviation -00 instead
+ of a long English-language string, as -00 is now the normal way to
+ represent an undefined time zone.
+
+ Several zones in Antarctica and the former Soviet Union, along
+ with zones intended for ships at sea that cannot use POSIX TZ
+ strings, now use numeric time zone abbreviations instead of
+ invented or obsolete alphanumeric abbreviations. The affected
+ zones are Antarctica/Casey, Antarctica/Davis,
+ Antarctica/DumontDUrville, Antarctica/Mawson, Antarctica/Rothera,
+ Antarctica/Syowa, Antarctica/Troll, Antarctica/Vostok,
+ Asia/Anadyr, Asia/Ashgabat, Asia/Baku, Asia/Bishkek, Asia/Chita,

+ Etc/GMT+9, Etc/GMT+10, Etc/GMT+11, Etc/GMT+12, Europe/Kaliningrad,
+ Europe/Minsk, Europe/Samara, Europe/Volgograd, and
+ Indian/Kerguelen. For Europe/Moscow the invented abbreviation MSM
+ was replaced by +05, whereas MSK and MSD were kept as they are not
+ our invention and are widely used.
+
+ Changes to zone names
+
+ Rename Asia/Rangoon to Asia/Yangon, with a backward compatibility link.
+ (Thanks to David Massoud.)
+
+ Changes to code
+
+ zic no longer generates binary files containing POSIX TZ-like
+ strings that disagree with the local time type after the last
+ explicit transition in the data. This fixes a bug with
+ Africa/Casablanca and Africa/El_Aaiun in some year-2037 time
+ stamps on the reference platform. (Thanks to Alexander Belopolsky
+ for reporting the bug and suggesting a way forward.)
+
+ If the installed localtime and/or posixrules files are symbolic
+ links, zic now keeps them symbolic links when updating them, for
+ compatibility with platforms like OpenSUSE where other programs
+ configure these files as symlinks.
+
+ zic now avoids hard linking to symbolic links, avoids some
+ unnecessary mkdir and stat system calls, and uses shorter file
+ names internally.
+
+ zdump has a new -i option to generate transitions in a
+ more-compact but still human-readable format. This option is
+ experimental, and the output format may change in future versions.
+ (Thanks to Jon Skeet for suggesting that an option was needed,
+ and thanks to Tim Parenti and Chris Rovick for further comments.)
+
+ Changes to build procedure
+
+ An experimental distribution format is available, in addition
+ to the traditional format which will continue to be distributed.
+ The new format is a tarball tzdb-VERSION.tar.lz with signature
+ file tzdb-VERSION.tar.lz.asc. It unpacks to a top-level directory
+ tzdb-VERSION containing the code and data of the traditional
+ two-tarball format, along with extra data that may be useful.
+ (Thanks to Antonio Diaz Diaz, Oscar van Vlijmen, and many others
+ for comments about the experimental format.)
+
+ The release version number is now more accurate in the usual case
+ where releases are built from a Git repository. For example, if
+ 23 commits and some working-file changes have been made since
+ release 2016g, the version number is now something like
+ '2016g-23-g50556e3-dirty' instead of the misleading '2016g'.
+ Tagged releases use the same version number format as before,
+ e.g., '2016g'. To support the more-accurate version number, its
+ specification has moved from a line in the Makefile to a new
+ source file 'version'.
+
+ The experimental distribution contains a file to2050.tzs that
+ contains what should be the output of 'zdump -i -c 2050' on
+ primary zones. If this file is available, 'make check' now checks
+ that zdump generates this output.
+
+ 'make check_web' now works on Fedora-like distributions.
+
+ Changes to documentation and commentary
+
+ tzfile.5 now documents the new restriction on POSIX TZ-like
+ strings that is now implemented by zic.
+
+ Comments now cite URLs for some 1917-1921 Russian DST decrees.
+ (Thanks to Alexander Belopolsky.)
+
+ tz-link.htm mentions JuliaTime (thanks to Curtis Vogt) and Time4J
+ (thanks to Meno Hochschild) and ThreeTen-Extra, and its
+ description of Java 8 has been brought up to date (thanks to
+ Stephen Colebourne). Its description of local time on Mars has
+ been updated to match current practice, and URLs have been updated
+ and some obsolete ones removed.

#
-# I recollect before the recent change the government announcements
-# mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
-# Time and no mention was made about the abbreviation.

-# If we look at Sri Lanka Department of Government's "Official News

-# use SLT as abbreviation in time stamp at the beginning of each news

-#
-# Within Sri Lanka I think LKT is well known among computer users and

+As mentioned in Theory.html, although calendrical issues are out of
+scope for tzdb, they indicate the sort of problems that we would run
+into if we extended tzdb further into the past. The following
+information and sources go beyond Theory.html's brief discussion.

+French Revolutionary calendar used 1793-11-24 through 1805-12-31,

+From Chris Carrier (1996-12-02):
+On 1929-10-01 the Soviet Union instituted an "Eternal Calendar"
+with 30-day months plus 5 holidays, with a 5-day week.
+On 1931-12-01 it changed to a 6-day week; in 1934 it reverted to the
+Gregorian calendar while retaining the 6-day week; on 1940-06-27 it
+reverted to the 7-day week. With the 6-day week the usual days
+off were the 6th, 12th, 18th, 24th and 30th of the month.

+<news:1996Jul6.012937.29190 at sq.com>
+Date: 1996-07-06
+
+In 1700, Denmark made the transition from Julian to Gregorian. Sweden
+decided to *start* a transition in 1700 as well, but rather than have one of
+those unsightly calendar gaps :-), they simply decreed that the next leap
+year after 1696 would be in 1744 - putting the whole country on a calendar
+different from both Julian and Gregorian for a period of 40 years.
+
+However, in 1704 something went wrong and the plan was not carried through;
+they did, after all, have a leap year that year. And one in 1708. In 1712
+they gave it up and went back to Julian, putting 30 days in February that
+year!...
+
+Then in 1753, Sweden made the transition to Gregorian in the usual manner,
+getting there only 13 years behind the original schedule.
+
+(A previous posting of this story was challenged, and Swedish readers
+produced the following references to support it: "Tideräkning och historia"
+by Natanael Beckman (1924) and "Tid, en bok om tideräkning och
+kalenderväsen" by Lars-Olof Lodén (1968).

-# Apparent noon times below are for Riyadh; they're a bit off for other places.
-# Times were computed using formulas in the U.S. Naval Observatory's
-# Almanac for Computers 1988; the formulas "will give EqT to an accuracy of
-# [plus or minus two] seconds during the current year."
-#
-# Rounding to the nearest five seconds results in fewer than

-# Apparent noon times below are for Riyadh; they're a bit off for other places.
-# Times were computed using a formula provided by the U. S. Naval Observatory:
-# eqt = -105.8 * sin(l) + 596.2 * sin(2 * l) + 4.4 * sin(3 * l)
-# -12.7 * sin(4 * l) - 429.0 * cos(l) - 2.1 * cos (2 * l)
-# + 19.3 * cos(3 * l);
-# where l is the "mean longitude of the Sun" given by
-# l = 279.642 degrees + 0.985647 * d
-# and d is the interval in days from January 0, 0 hours Universal Time
-# (equaling the day of the year plus the fraction of a day from zero hours).
-# The accuracy of the formula is plus or minus three seconds.
-#
-# Rounding to the nearest five seconds results in fewer than
-# 256 different "time types"--a limit that's faced because time types are
-# stored on disk as unsigned chars.

# Uruguay
# From Paul Eggert (1993-11-18):
# Uruguay wins the prize for the strangest peacetime manipulation of the rules.

+# From Tim Parenti (2018-02-20), per Jeremie Bonjour (2018-01-31) and Michael
+# Deckers (2018-02-20):

+# Page 36 of Almanaque 2018, published by the Oceanography, Hydrography, and
+# Meteorology Service of the Uruguayan Navy, seems to give many transitions
+# with greater clarity than we've had before. It directly references many laws
+# and decrees which are, in turn, referenced below. They can be viewed in the
+# public archives of the Diario Oficial (in Spanish) at
+# http://www.impo.com.uy/diariooficial/
+#
+# Ley No. 3920 of 1908-06-10 placed the determination of legal time under the
+# auspices of the National Institute for the Prediction of Time. It is unclear
+# exactly what offset was used during this period, though Ley No. 7200 of
+# 1920-04-23 used the Observatory of the National Meteorological Institute in
+# Montevideo (34° 54' 33" S, 56° 12' 45" W) as its reference meridian,
+# retarding legal time by 15 minutes 9 seconds from 1920-04-30 24:00,
+# resulting in UT-04. Assume the corresponding LMT of UT-03:44:51 (given on
+# page 725 of the Proceedings of the Second Pan-American Scientific Congress,
+# 1915-1916) was in use, and merely became official from 1908-06-10.
+# https://www.impo.com.uy/diariooficial/1908/06/18/12
+# https://www.impo.com.uy/diariooficial/1920/04/27/9
+#
+# Ley No. 7594 of 1923-06-28 specified legal time as Observatory time advanced
+# by 44 minutes 51 seconds (UT-03) "from 30 September to 31 March", and by 14
+# minutes 51 seconds (UT-03:30) "the rest of the year"; a message from the
+# National Council of Administration the same day, published directly below the
+# law in the Diario Oficial, specified the first transition to be 1923-09-30
+# 24:00. This effectively established standard time at UT-03:30 with 30
+# minutes DST. Assume transitions at 24:00 on the specified days until Ley No.
+# 7919 of 1926-03-05 ended this arrangement, repealing all "laws and other
+# provisions which oppose" it, resulting in year-round UT-03:30; a Resolución
+# of 1926-03-11 puts the final transition at 1926-03-31 24:00, the same as it
+# would have been under the previous law.

+#
+# It appears Ley No. 9122 of 1933 was never published as such in the Diario
+# Oficial, but instead appeared as Document 26 in the Diario on Friday
+# 1933-10-27 as a decree made Monday 1933-10-23 and filed under the Ministry of
+# National Defense. It reinstituted a DST of 30 minutes (to UT-03) "from the
+# last Sunday of October...until the last Saturday of March." In accordance
+# with this provision, the first transition was explicitly specified in Article
+# 2 of the decree as Saturday 1933-10-28 at 24:00; that is, Sunday 1933-10-29
+# at 00:00. Assume transitions at 00:00 Sunday throughout.
+#
+# Departing from the matter-of-fact nature of previous timekeeping laws, the
+# 1933 decree "consider[s] the advantages of...the advance of legal time":
+#
+# "Whereas: The measure adopted by almost all nations at the time of the last
+# World War still persists in North America and Europe, precisely because of
+# the economic, hygienic, and social advantages derived from such an
+# emergency measure...
+#
+# Whereas: The advance of the legal time during the summer seasons, by
+# displacing social activity near sunrise, favors the citizen populations
+# and especially the society that creates and works..."
+#
+# It further specified that "necessary measures" be taken to ensure that
+# "public spectacles finish, in general, before [01:00]."

+# From Tim Parenti (2018-02-15):
+# Most of the Rules below, and their contemporaneous Zone lines, have been
+# updated simply to match the Almanaque 2018. Although the document does not
+# list exact transition times, midnight transitions were already present in our
+# data here for all transitions through 2004-09, and this is both consistent
+# with prior transitions and verified in several decrees marked below between
+# 1939-09 and 2004-09, wherein the relevant text was typically of the form:
+#
+# "From 0 hours on [date], the legal time of the entire Republic will be...
+#
+# In accordance with [the preceding], on [previous date] at 24 hours, all
+# clocks throughout the Republic will be [advanced/retarded] by..."
+#
+# It is possible that there is greater specificity to be found for the Rules
+# below, but it is buried in no fewer than 40 different decrees individually
+# referenced by the Almanaque for the period from 1939-09 to 2014-09.
+# Four-fifths of these were promulgated less than two weeks before taking
+# effect; more than half within a week and none more than 5 weeks. Only the
+# handful with comments below have been checked with any thoroughness.

+Although 1970 is a somewhat-arbitrary cutoff, there are significant
+challenges to moving the cutoff earlier even by a decade or two, due
+to the wide variety of local practices before computer timekeeping
+became prevalent.
+</p>
+
+<p>
+Clock transitions before 1970 are recorded for each such location,
+because most systems support timestamps before 1970 and could
+misbehave if data entries were omitted for pre-1970 transitions.
+However, the database is not designed for and does not suffice for
+applications requiring accurate handling of all past times everywhere,
+as it would take far too much effort and guesswork to record all
+details of pre-1970 civil timekeeping.
+Although some information outside the scope of the database is
+collected in a file <code>backzone</code> that is distributed along
+with the database proper, this file is less reliable and does not
+necessarily follow database guidelines.
+</p>
+
+<p>
+As described below, reference source code for using the
+<code><abbr>tz</abbr></code> database is also available.
+The <code><abbr>tz</abbr></code> code is upwards compatible with <a
+href="https://en.wikipedia.org/wiki/POSIX">POSIX</a>, an international
+standard for <a
+href="https://en.wikipedia.org/wiki/Unix">UNIX</a>-like systems.
+As of this writing, the current edition of POSIX is: <a
+href="http://pubs.opengroup.org/onlinepubs/9699919799/"> The Open
+Group Base Specifications Issue 7</a>, IEEE Std 1003.1-2017, 2018
+Edition.
+Because the database's scope encompasses real-world changes to civil
+timekeeping, its model for describing time is more complex than the
+standard and daylight saving times supported by POSIX.
+A <code><abbr>tz</abbr></code> region corresponds to a ruleset that can
+have more than two changes per year, these changes need not merely
+flip back and forth between two alternatives, and the rules themselves
+can change at times.
+Whether and when a <code><abbr>tz</abbr></code> region changes its
+clock, and even the region's notional base offset from UTC, are variable.
+It does not always make sense to talk about a region's
+"base offset", since it is not necessarily a single number.

+<section>
+ <h2 id="naming">Names of time zone rulesets</h2>
+<p>
+Each <code><abbr>tz</abbr></code> region has a unique name that
+corresponds to a set of time zone rules.
+Inexperienced users are not expected to select these names unaided.
+Distributors should provide documentation and/or a simple selection
+interface that explains the names; for one example, see the
+<code>tzselect</code> program in the <code><abbr>tz</abbr></code> code.
+The <a href="http://cldr.unicode.org/">Unicode Common Locale Data
+Repository</a> contains data that may be useful for other selection
+interfaces.
+</p>
+
+<p>
+The naming conventions attempt to strike a balance
+among the following goals:
+</p>
+
+<ul>
+ <li>
+ Uniquely identify every region where clocks have agreed since 1970.
+ This is essential for the intended use: static clocks keeping local
+ civil time.
+ </li>
+ <li>
+ Indicate to experts where that region is.
+ </li>
+ <li>
+ Be robust in the presence of political changes.
+ For example, names of countries are ordinarily not used, to avoid
+ incompatibilities when countries change their name (e.g.,
+ Zaire→Congo) or when locations change countries (e.g., Hong
+ Kong from UK colony to China).
+ </li>
+ <li>
+ Be portable to a wide variety of implementations.
+ </li>
+ <li>
+ Use a consistent naming conventions over the entire world.
+ </li>
+</ul>
+
+<p>
+Names normally have the form
+<var>AREA</var><code>/</code><var>LOCATION</var>, where
+<var>AREA</var> is the name of a continent or ocean, and
+<var>LOCATION</var> is the name of a specific location within that
+region.
+North and South America share the same area, '<code>America</code>'.
+Typical names are '<code>Africa/Cairo</code>',
+'<code>America/New_York</code>', and '<code>Pacific/Honolulu</code>'.
+Some names are further qualified to help avoid confusion; for example,
+'<code>America/Indiana/Petersburg</code>' distinguishes Petersburg,
+Indiana from other Petersburgs in America.
+</p>
+
+<p>
+Here are the general guidelines used for
+choosing <code><abbr>tz</abbr></code> region names,
+in decreasing order of importance:
+</p>
+
+<ul>
+ <li>
+ Use only valid POSIX file name components (i.e., the parts of
+ names other than '<code>/</code>').
+ Do not use the file name components '<code>.</code>' and
+ '<code>..</code>'.
+ Within a file name component, use only <a
+ href="https://en.wikipedia.org/wiki/ASCII">ASCII</a> letters,
+ '<code>.</code>', '<code>-</code>' and '<code>_</code>'.
+ Do not use digits, as that might create an ambiguity with <a
+ href="http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap08.html#tag_08_03">POSIX
+ <code>TZ</code> strings</a>.
+ A file name component must not exceed 14 characters or start with
+ '<code>-</code>'.
+ E.g., prefer <code>Asia/Brunei</code> to
+ <code>Asia/Bandar_Seri_Begawan</code>.
+ Exceptions: see the discussion of legacy names below.
+ </li>
+ <li>
+ A name must not be empty, or contain '<code>//</code>', or
+ start or end with '<code>/</code>'.
+ </li>
+ <li>
+ Do not use names that differ only in case.
+ Although the reference implementation is case-sensitive, some
+ other implementations are not, and they would mishandle names
+ differing only in case.
+ </li>
+ <li>
+ If one name <var>A</var> is an initial prefix of another
+ name <var>AB</var> (ignoring case), then <var>B</var> must not
+ start with '<code>/</code>', as a regular file cannot have the
+ same name as a directory in POSIX.
+ For example, <code>America/New_York</code> precludes
+ <code>America/New_York/Bronx</code>.
+ </li>
+ <li>
+ Uninhabited regions like the North Pole and Bouvet Island
+ do not need locations, since local time is not defined there.
+ </li>
+ <li>
+ There should typically be at least one name for each <a
+ href="https://en.wikipedia.org/wiki/ISO_3166-1"><abbr
+ title="International Organization for Standardization">ISO</abbr>
+ 3166-1</a> officially assigned two-letter code for an inhabited
+ country or territory.
+ </li>
+ <li>
+ If all the clocks in a region have agreed since 1970,
+ do not bother to include more than one location
+ even if subregions' clocks disagreed before 1970.
+ Otherwise these tables would become annoyingly large.
+ </li>
+ <li>
+ If a name is ambiguous, use a less ambiguous alternative;
+ e.g., many cities are named San José and Georgetown, so
+ prefer <code>America/Costa_Rica</code> to
+ <code>America/San_Jose</code> and <code>America/Guyana</code>
+ to <code>America/Georgetown</code>.
+ </li>
+ <li>
+ Keep locations compact.
+ Use cities or small islands, not countries or regions, so that any
+ future changes do not split individual locations into different
+ <code><abbr>tz</abbr></code> regions.
+ E.g., prefer <code>Europe/Paris</code> to <code>Europe/France</code>,
+ since
+ <a href="https://en.wikipedia.org/wiki/Time_in_France#History">France
+ has had multiple time zones</a>.
+ </li>
+ <li>
+ Use mainstream English spelling, e.g., prefer
+ <code>Europe/Rome</code> to <code>Europe/Roma</code>, and
+ prefer <code>Europe/Athens</code> to the Greek
+ <code>Europe/Αθήνα</code> or the Romanized
+ <code>Europe/Athína</code>.
+ The POSIX file name restrictions encourage this guideline.
+ </li>
+ <li>
+ Use the most populous among locations in a region,
+ e.g., prefer <code>Asia/Shanghai</code> to
+ <code>Asia/Beijing</code>.
+ Among locations with similar populations, pick the best-known
+ location, e.g., prefer <code>Europe/Rome</code> to
+ <code>Europe/Milan</code>.
+ </li>
+ <li>
+ Use the singular form, e.g., prefer <code>Atlantic/Canary</code> to
+ <code>Atlantic/Canaries</code>.
+ </li>
+ <li>
+ Omit common suffixes like '<code>_Islands</code>' and
+ '<code>_City</code>', unless that would lead to ambiguity.
+ E.g., prefer <code>America/Cayman</code> to
+ <code>America/Cayman_Islands</code> and
+ <code>America/Guatemala</code> to
+ <code>America/Guatemala_City</code>, but prefer
+ <code>America/Mexico_City</code> to
+ <code>America/Mexico</code>
+ because <a href="https://en.wikipedia.org/wiki/Time_in_Mexico">the
+ country of Mexico has several time zones</a>.
+ </li>
+ <li>
+ Use '<code>_</code>' to represent a space.
+ </li>
+ <li>
+ Omit '<code>.</code>' from abbreviations in names.
+ E.g., prefer <code>Atlantic/St_Helena</code> to
+ <code>Atlantic/St._Helena</code>.
+ </li>
+ <li>
+ Do not change established names if they only marginally violate
+ the above guidelines.
+ For example, do not change the existing name <code>Europe/Rome</code> to
+ <code>Europe/Milan</code> merely because Milan's population has grown
+ to be somewhat greater than Rome's.
+ </li>
+ <li>
+ If a name is changed, put its old spelling in the
+ '<code>backward</code>' file.
+ This means old spellings will continue to work.
+ </li>
+</ul>
+
+<p>
+The file '<code>zone1970.tab</code>' lists geographical locations used
+to name <code><abbr>tz</abbr></code> regions.
+It is intended to be an exhaustive list of names for geographic
+regions as described above; this is a subset of the names in the data.
+Although a '<code>zone1970.tab</code>' location's
+<a href="https://en.wikipedia.org/wiki/Longitude">longitude</a>
+corresponds to
+its <a href="https://en.wikipedia.org/wiki/Local_mean_time">local mean
+time (<abbr>LMT</abbr>)</a> offset with one hour for every 15°
+east longitude, this relationship is not exact.
+</p>
+
+<p>
+Older versions of this package used a different naming scheme,
+and these older names are still supported.
+See the file '<code>backward</code>' for most of these older names
+(e.g., '<code>US/Eastern</code>' instead of '<code>America/New_York</code>').
+The other old-fashioned names still supported are
+'<code>WET</code>', '<code>CET</code>', '<code>MET</code>', and
+'<code>EET</code>' (see the file '<code>europe</code>').
+</p>
+
+<p>
+Older versions of this package defined legacy names that are
+incompatible with the first guideline of location names, but which are
+still supported.
+These legacy names are mostly defined in the file
+'<code>etcetera</code>'.
+Also, the file '<code>backward</code>' defines the legacy names
+'<code>GMT0</code>', '<code>GMT-0</code>' and '<code>GMT+0</code>',
+and the file '<code>northamerica</code>' defines the legacy names
+'<code>EST5EDT</code>', '<code>CST6CDT</code>',
+'<code>MST7MDT</code>', and '<code>PST8PDT</code>'.
+</p>
+
+<p>
+Excluding '<code>backward</code>' should not affect the other data.
+If '<code>backward</code>' is excluded, excluding
+'<code>etcetera</code>' should not affect the remaining data.

+
+<section>
+ <h2 id="abbreviations">Time zone abbreviations</h2>
+<p>
+When this package is installed, it generates time zone abbreviations
+like '<code>EST</code>' to be compatible with human tradition and POSIX.
+Here are the general guidelines used for choosing time zone abbreviations,
+in decreasing order of importance:
+</p>
+
+<ul>
+ <li>
+ Use three to six characters that are ASCII alphanumerics or
+ '<code>+</code>' or '<code>-</code>'.
+ Previous editions of this database also used characters like
+ space and '<code>?</code>', but these characters have a
+ special meaning to the
+ <a href="https://en.wikipedia.org/wiki/Unix_shell">UNIX shell</a>
+ and cause commands like
+ '<code><a href="http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#set">set</a>
+ `<a href="http://pubs.opengroup.org/onlinepubs/9699919799/utilities/date.html">date</a>`</code>'
+ to have unexpected effects.
+ Previous editions of this guideline required upper-case letters, but the
+ Congressman who introduced
+ <a href="https://en.wikipedia.org/wiki/Chamorro_Time_Zone">Chamorro
+ Standard Time</a> preferred "ChST", so lower-case letters are now
+ allowed.
+ Also, POSIX from 2001 on relaxed the rule to allow '<code>-</code>',
+ '<code>+</code>', and alphanumeric characters from the portable
+ character set in the current locale.
+ In practice ASCII alphanumerics and '<code>+</code>' and
+ '<code>-</code>' are safe in all locales.
+
+ <p>
+ In other words, in the C locale the POSIX extended regular
+ expression <code>[-+[:alnum:]]{3,6}</code> should match the
+ abbreviation.
+ This guarantees that all abbreviations could have been specified by a
+ POSIX <code>TZ</code> string.
+ </p>
+ </li>
+ <li>
+ Use abbreviations that are in common use among English-speakers,
+ e.g., 'EST' for Eastern Standard Time in North America.
+ We assume that applications translate them to other languages
+ as part of the normal localization process; for example,
+ a French application might translate 'EST' to 'HNE'.
+
+ <p>
+ <small>These abbreviations (for standard/daylight/etc. time) are:
+ ACST/ACDT Australian Central,
+ AST/ADT/APT/AWT/ADDT Atlantic,
+ AEST/AEDT Australian Eastern,
+ AHST/AHDT Alaska-Hawaii,
+ AKST/AKDT Alaska,
+ AWST/AWDT Australian Western,
+ BST/BDT Bering,
+ CAT/CAST Central Africa,
+ CET/CEST/CEMT Central European,
+ ChST Chamorro,
+ CST/CDT/CWT/CPT/CDDT Central [North America],
+ CST/CDT China,

+ EET/EEST Eastern European,
+ GST Guam,
+ HST/HDT Hawaii,
+ HKT/HKST Hong Kong,
+ IST India,
+ IST/GMT Irish,
+ IST/IDT/IDDT Israel,
+ JST/JDT Japan,
+ KST/KDT Korea,
+ MET/MEST Middle European (a backward-compatibility alias for
+ Central European),
+ MSK/MSD Moscow,
+ MST/MDT/MWT/MPT/MDDT Mountain,
+ NST/NDT/NWT/NPT/NDDT Newfoundland,
+ NST/NDT/NWT/NPT Nome,
+ NZMT/NZST New Zealand through 1945,
+ NZST/NZDT New Zealand 1946–present,
+ PKT/PKST Pakistan,
+ PST/PDT/PWT/PPT/PDDT Pacific,
+ SAST South Africa,
+ SST Samoa,
+ WAT/WAST West Africa,
+ WET/WEST/WEMT Western European,
+ WIB Waktu Indonesia Barat,
+ WIT Waktu Indonesia Timur,
+ WITA Waktu Indonesia Tengah,
+ YST/YDT/YWT/YPT/YDDT Yukon</small>.
+ </p>
+ </li>
+ <li>
+ <p>
+ For times taken from a city's longitude, use the
+ traditional <var>x</var>MT notation.
+ The only abbreviation like this in current use is '<abbr>GMT</abbr>'.
+ The others are for timestamps before 1960,
+ except that Monrovia Mean Time persisted until 1972.
+ Typically, numeric abbreviations (e.g., '<code>-</code>004430' for
+ MMT) would cause trouble here, as the numeric strings would exceed
+ the POSIX length limit.
+ </p>
+
+ <p>
+ <small>These abbreviations are:
+ AMT Amsterdam, Asunción, Athens;
+ BMT Baghdad, Bangkok, Batavia, Bern, Bogotá, Bridgetown, Brussels,
+ Bucharest;
+ CMT Calamarca, Caracas, Chisinau, Colón, Copenhagen, Córdoba;
+ DMT Dublin/Dunsink;
+ EMT Easter;
+ FFMT Fort-de-France;
+ FMT Funchal;
+ GMT Greenwich;
+ HMT Havana, Helsinki, Horta, Howrah;
+ IMT Irkutsk, Istanbul;
+ JMT Jerusalem;
+ KMT Kaunas, Kiev, Kingston;
+ LMT Lima, Lisbon, local, Luanda;
+ MMT Macassar, Madras, Malé, Managua, Minsk, Monrovia, Montevideo,
+ Moratuwa, Moscow;
+ PLMT Phù Liễn;
+ PMT Paramaribo, Paris, Perm, Pontianak, Prague;
+ PMMT Port Moresby;
+ QMT Quito;
+ RMT Rangoon, Riga, Rome;
+ SDMT Santo Domingo;
+ SJMT San José;
+ SMT Santiago, Simferopol, Singapore, Stanley;
+ TBMT Tbilisi;
+ TMT Tallinn, Tehran;
+ WMT Warsaw</small>.
+ </p>
+
+ <p>
+ <small>A few abbreviations also follow the pattern that
+ <abbr>GMT<abbr>/<abbr>BST</abbr> established for time in the UK.
+ They are:
+ CMT/BST for Calamarca Mean Time and Bolivian Summer Time
+ 1890–1932,
+ DMT/IST for Dublin/Dunsink Mean Time and Irish Summer Time
+ 1880–1916,
+ MMT/MST/MDST for Moscow 1880–1919, and
+ RMT/LST for Riga Mean Time and Latvian Summer time 1880–1926.
+ An extra-special case is SET for Swedish Time (<em>svensk
+ normaltid</em>) 1879–1899, 3° west of the Stockholm
+ Observatory.</small>
+ </p>
+ </li>
+ <li>
+ Use '<abbr>LMT</abbr>' for local mean time of locations before the
+ introduction of standard time; see "<a href="#scope">Scope of the
+ <code><abbr>tz</abbr></code> database</a>".
+ </li>
+ <li>
+ If there is no common English abbreviation, use numeric offsets like
+ <code>-</code>05 and <code>+</code>0830 that are generated
+ by <code>zic</code>'s <code>%z</code> notation.
+ </li>
+ <li>
+ Use current abbreviations for older timestamps to avoid confusion.
+ For example, in 1910 a common English abbreviation for time
+ in central Europe was 'MEZ' (short for both "Middle European
+ Zone" and for "Mitteleuropäische Zeit" in German).
+ Nowadays 'CET' ("Central European Time") is more common in
+ English, and the database uses 'CET' even for circa-1910
+ timestamps as this is less confusing for modern users and avoids
+ the need for determining when 'CET' supplanted 'MEZ' in common
+ usage.
+ </li>
+ <li>
+ Use a consistent style in a <code><abbr>tz</abbr></code> region's history.
+ For example, if history tends to use numeric
+ abbreviations and a particular entry could go either way, use a
+ numeric abbreviation.
+ </li>
+ <li>
+ Use
+ <a href="https://en.wikipedia.org/wiki/Universal_Time">Universal Time</a>
+ (<abbr>UT</abbr>) (with time zone abbreviation '<code>-</code>00') for
+ locations while uninhabited.
+ The leading '<code>-</code>' is a flag that the <abbr>UT</abbr> offset is in
+ some sense undefined; this notation is derived
+ from <a href="https://tools.ietf.org/html/rfc3339">Internet
+ <abbr title="Request For Comments">RFC 3339</a>.
+ </li>
+</ul>
+
+<p>
+Application writers should note that these abbreviations are ambiguous
+in practice: e.g., 'CST' means one thing in China and something else
+in North America, and 'IST' can refer to time in India, Ireland or
+Israel.
+To avoid ambiguity, use numeric <abbr>UT</abbr> offsets like
+'<code>-</code>0600' instead of time zone abbreviations like 'CST'.

+ <h2 id="accuracy">Accuracy of the <code><abbr>tz</abbr></code> database</h2>
+<p>
+The <code><abbr>tz</abbr></code> database is not authoritative, and it
+surely has errors.
+Corrections are welcome and encouraged; see the file <code>CONTRIBUTING</code>.
+Users requiring authoritative data should consult national standards
+bodies and the references cited in the database's comments.
+</p>
+
+<p>
+Errors in the <code><abbr>tz</abbr></code> database arise from many sources:
+</p>
+
+<ul>
+ <li>
+ The <code><abbr>tz</abbr></code> database predicts future
+ timestamps, and current predictions
+ will be incorrect after future governments change the rules.
+ For example, if today someone schedules a meeting for 13:00 next
+ October 1, Casablanca time, and tomorrow Morocco changes its
+ daylight saving rules, software can mess up after the rule change
+ if it blithely relies on conversions made before the change.
+ </li>
+ <li>
+ The pre-1970 entries in this database cover only a tiny sliver of how
+ clocks actually behaved; the vast majority of the necessary
+ information was lost or never recorded.
+ Thousands more <code><abbr>tz</abbr></code> regions would be needed if
+ the <code><abbr>tz</abbr></code> database's scope were extended to
+ cover even just the known or guessed history of standard time; for
+ example, the current single entry for France would need to split
+ into dozens of entries, perhaps hundreds.
+ And in most of the world even this approach would be misleading
+ due to widespread disagreement or indifference about what times
+ should be observed.
+ In her 2015 book
+ <cite><a
+ href="http://www.hup.harvard.edu/catalog.php?isbn=9780674286146">The
+ Global Transformation of Time, 1870–1950</a></cite>,
+ Vanessa Ogle writes
+ "Outside of Europe and North America there was no system of time
+ zones at all, often not even a stable landscape of mean times,
+ prior to the middle decades of the twentieth century".
+ See: Timothy Shenk, <a
+href="https://www.dissentmagazine.org/blog/booked-a-global-history-of-time-vanessa-ogle">Booked:
+ A Global History of Time</a>. <cite>Dissent</cite> 2015-12-17.
+ </li>
+ <li>
+ Most of the pre-1970 data entries come from unreliable sources, often
+ astrology books that lack citations and whose compilers evidently
+ invented entries when the true facts were unknown, without
+ reporting which entries were known and which were invented.
+ These books often contradict each other or give implausible entries,
+ and on the rare occasions when they are checked they are
+ typically found to be incorrect.
+ </li>
+ <li>
+ For the UK the <code><abbr>tz</abbr></code> database relies on
+ years of first-class work done by
+ Joseph Myers and others; see
+ "<a href="https://www.polyomino.org.uk/british-time/">History of
+ legal time in Britain</a>".
+ Other countries are not done nearly as well.
+ </li>
+ <li>
+ Sometimes, different people in the same city maintain clocks
+ that differ significantly.
+ Historically, railway time was used by railroad companies (which
+ did not always
+ agree with each other), church-clock time was used for birth
+ certificates, etc.
+ More recently, competing political groups might disagree about
+ clock settings. Often this is merely common practice, but
+ sometimes it is set by law.
+ For example, from 1891 to 1911 the <abbr>UT</abbr> offset in France
+ was legally <abbr>UT</abbr> +00:09:21 outside train stations and
+ <abbr>UT</abbr> +00:04:21 inside. Other examples include
+ Chillicothe in 1920, Palm Springs in 1946/7, and Jerusalem and
+ Ürümqi to this day.
+ </li>
+ <li>
+ Although a named location in the <code><abbr>tz</abbr></code>
+ database stands for the containing region, its pre-1970 data
+ entries are often accurate for only a small subset of that region.
+ For example, <code>Europe/London</code> stands for the United
+ Kingdom, but its pre-1847 times are valid only for locations that
+ have London's exact meridian, and its 1847 transition
+ to <abbr>GMT</abbr> is known to be valid only for the L&NW and
+ the Caledonian railways.
+ </li>
+ <li>
+ The <code><abbr>tz</abbr></code> database does not record the
+ earliest time for which a <code><abbr>tz</abbr></code> region's
+ data entries are thereafter valid for every location in the region.
+ For example, <code>Europe/London</code> is valid for all locations
+ in its region after <abbr>GMT</abbr> was made the standard time,
+ but the date of standardization (1880-08-02) is not in the
+ <code><abbr>tz</abbr></code> database, other than in commentary.
+ For many <code><abbr>tz</abbr></code> regions the earliest time of
+ validity is unknown.
+ </li>
+ <li>
+ The <code><abbr>tz</abbr></code> database does not record a
+ region's boundaries, and in many cases the boundaries are not known.
+ For example, the <code><abbr>tz</abbr></code> region
+ <code>America/Kentucky/Louisville</code> represents a region
+ around the city of Louisville, the boundaries of which are
+ unclear.
+ </li>
+ <li>
+ Changes that are modeled as instantaneous transitions in the
+ <code><abbr>tz</abbr></code>
+ database were often spread out over hours, days, or even decades.
+ </li>
+ <li>
+ Even if the time is specified by law, locations sometimes
+ deliberately flout the law.
+ </li>
+ <li>
+ Early timekeeping practices, even assuming perfect clocks, were
+ often not specified to the accuracy that the
+ <code><abbr>tz</abbr></code> database requires.
+ </li>
+ <li>
+ Sometimes historical timekeeping was specified more precisely
+ than what the <code><abbr>tz</abbr></code> code can handle.
+ For example, from 1909 to 1937 <a
+ href="https://www.staff.science.uu.nl/~gent0113/wettijd/wettijd.htm"
+ hreflang="nl">Netherlands clocks</a> were legally Amsterdam Mean
+ Time (estimated to be <abbr>UT</abbr>
+ +00:19:32.13), but the <code><abbr>tz</abbr></code>
+ code cannot represent the fractional second.
+ In practice these old specifications were rarely if ever
+ implemented to subsecond precision.
+ </li>
+ <li>
+ Even when all the timestamp transitions recorded by the
+ <code><abbr>tz</abbr></code> database are correct, the
+ <code><abbr>tz</abbr></code> rules that generate them may not
+ faithfully reflect the historical rules.
+ For example, from 1922 until World War II the UK moved clocks
+ forward the day following the third Saturday in April unless that
+ was Easter, in which case it moved clocks forward the previous
+ Sunday.
+ Because the <code><abbr>tz</abbr></code> database has no
+ way to specify Easter, these exceptional years are entered as
+ separate <code><abbr>tz</abbr> Rule</code> lines, even though the
+ legal rules did not change.
+ </li>
+ <li>
+ The <code><abbr>tz</abbr></code> database models pre-standard time
+ using the <a
+ href="https://en.wikipedia.org/wiki/Proleptic_Gregorian_calendar">proleptic
+ Gregorian calendar</a> and local mean time, but many people used
+ other calendars and other timescales.
+ For example, the Roman Empire used
+ the <a href="https://en.wikipedia.org/wiki/Julian_calendar">Julian
+ calendar</a>,
+ and <a href="https://en.wikipedia.org/wiki/Roman_timekeeping">Roman
+ timekeeping</a> had twelve varying-length daytime hours with a
+ non-hour-based system at night.
+ </li>
+ <li>
+ Early clocks were less reliable, and data entries do not represent
+ clock error.
+ </li>

+ The <code><abbr>tz</abbr></code> database assumes Universal Time
+ (<abbr>UT</abbr>) as an origin, even though <abbr>UT</abbr> is not

+ In the <code><abbr>tz</abbr></code> database commentary,
+ <abbr>UT</abbr> denotes a family of time standards that includes
+ Coordinated Universal Time (<abbr>UTC</abbr>) along with other
+ variants such as <abbr>UT1</abbr> and <abbr>GMT</abbr>,
+ with days starting at midnight.
+ Although <abbr>UT</abbr> equals <abbr>UTC</abbr> for modern

+ commentary uses the more-general abbreviation <abbr>UT</abbr> for
+ timestamps that might predate 1960.
+ Since <abbr>UT</abbr>, <abbr>UT1</abbr>, etc. disagree slightly,

+In short, many, perhaps most, of the <code><abbr>tz</abbr></code>

+should be unacceptable to anybody who cares about the facts.
+In particular, the <code><abbr>tz</abbr></code> database's

+<p>
+The <code><abbr>tz</abbr></code> code contains time and date functions
+that are upwards compatible with those of POSIX.
+Code compatible with this package is already
+<a href="tz-link.html#tzdb">part of many platforms</a>, where the
+primary use of this package is to update obsolete time-related files.
+To do this, you may need to compile the time zone compiler
+'<code>zic</code>' supplied with this package instead of using the
+system '<code>zic</code>', since the format of <code>zic</code>'s
+input is occasionally extended, and a platform may still be shipping
+an older <code>zic</code>.
+</p>
+
+<h3 id="POSIX">POSIX properties and limitations</h3>
+<ul>
+ <li>
+ <p>
+ In POSIX, time display in a process is controlled by the
+ environment variable <code>TZ</code>.
+ Unfortunately, the POSIX
+ <code>TZ</code> string takes a form that is hard to describe and
+ is error-prone in practice.
+ Also, POSIX <code>TZ</code> strings cannot deal with daylight
+ saving time rules not based on the Gregorian calendar (as in
+ Iran), or with situations where more than two time zone
+ abbreviations or <abbr>UT</abbr> offsets are used in an area.
+ </p>
+
+ <p>
+ The POSIX <code>TZ</code> string takes the following form:
+ </p>
+
+ <p>
+ <var>stdoffset</var>[<var>dst</var>[<var>offset</var>][<code>,</code><var>date</var>[<code>/</code><var>time</var>]<code>,</code><var>date</var>[<code>/</code><var>time</var>]]]
+ </p>
+
+ <p>
+ where:
+ </p>
+
+ <dl>
+ <dt><var>std</var> and <var>dst</var></dt><dd>
+ are 3 or more characters specifying the standard
+ and daylight saving time (<abbr>DST</abbr>) zone names.
+ Starting with POSIX.1-2001, <var>std</var> and <var>dst</var>
+ may also be in a quoted form like '<code><+09></code>';
+ this allows "<code>+</code>" and "<code>-</code>" in the names.
+ </dd>
+ <dt><var>offset</var></dt><dd>
+ is of the form
+ '<code>[±]<var>hh</var>:[<var>mm</var>[:<var>ss</var>]]</code>'
+ and specifies the offset west of <abbr>UT</abbr>.
+ '<var>hh</var>' may be a single digit;
+ 0≤<var>hh</var>≤24.
+ The default <abbr>DST</abbr> offset is one hour ahead of
+ standard time.
+ </dd>
+ <dt><var>date</var>[<code>/</code><var>time</var>]<code>,</code><var>date</var>[<code>/</code><var>time</var>]</dt><dd>
+ specifies the beginning and end of <abbr>DST</abbr>.
+ If this is absent, the system supplies its own ruleset
+ for <abbr>DST</abbr>, and its rules can differ from year to year;
+ typically <abbr>US</abbr> <abbr>DST</abbr> rules are used.
+ </dd>
+ <dt><var>time</var></dt><dd>
+ takes the form
+ '<var>hh</var><code>:</code>[<var>mm</var>[<code>:</code><var>ss</var>]]'
+ and defaults to 02:00.
+ This is the same format as the offset, except that a
+ leading '<code>+</code>' or '<code>-</code>' is not allowed.
+ </dd>
+ <dt><var>date</var></dt><dd>
+ takes one of the following forms:
+ <dl>
+ <dt>J<var>n</var> (1≤<var>n</var>≤365)</dt><dd>
+ origin-1 day number not counting February 29
+ </dd>
+ <dt><var>n</var> (0≤<var>n</var>≤365)</dt><dd>
+ origin-0 day number counting February 29 if present
+ </dd>
+ <dt><code>M</code><var>m</var><code>.</code><var>n</var><code>.</code><var>d</var>
+ (0[Sunday]≤<var>d</var>≤6[Saturday], 1≤<var>n</var>≤5,
+ 1≤<var>m</var>≤12)</dt><dd>
+ for the <var>d</var>th day of week <var>n</var> of
+ month <var>m</var> of the year, where week 1 is the first
+ week in which day <var>d</var> appears, and
+ '<code>5</code>' stands for the last week in which
+ day <var>d</var> appears (which may be either the 4th or
+ 5th week).
+ Typically, this is the only useful form; the <var>n</var>
+ and <code>J</code><var>n</var> forms are rarely used.
+ </dd>

+
+ <p>
+ Here is an example POSIX <code>TZ</code> string for New
+ Zealand after 2007.
+ It says that standard time (<abbr>NZST</abbr>) is 12 hours ahead
+ of <abbr>UT</abbr>, and that daylight saving time
+ (<abbr>NZDT</abbr>) is observed from September's last Sunday at
+ 02:00 until April's first Sunday at 03:00:
+ </p>
+
+ <pre><code>TZ='NZST-12NZDT,M9.5.0,M4.1.0/3'</code></pre>
+
+ <p>
+ This POSIX <code>TZ</code> string is hard to remember, and
+ mishandles some timestamps before 2008.
+ With this package you can use this instead:
+ </p>
+
+ <pre><code>TZ='Pacific/Auckland'</code></pre>
+ </li>
+ <li>
+ POSIX does not define the exact meaning of <code>TZ</code> values like
+ "<code>EST5EDT</code>".
+ Typically the current <abbr>US</abbr> <abbr>DST</abbr> rules
+ are used to interpret such values, but this means that the
+ <abbr>US</abbr> <abbr>DST</abbr> rules are compiled into each
+ program that does time conversion.
+ This means that when
+ <abbr>US</abbr> time conversion rules change (as in the United
+ States in 1987), all programs that do time conversion must be
+ recompiled to ensure proper results.
+ </li>
+ <li>
+ The <code>TZ</code> environment variable is process-global, which
+ makes it hard to write efficient, thread-safe applications that
+ need access to multiple time zone rulesets.
+ </li>
+ <li>
+ In POSIX, there is no tamper-proof way for a process to learn the
+ system's best idea of local wall clock.
+ (This is important for applications that an administrator wants
+ used only at certain times – without regard to whether the
+ user has fiddled the
+ <code>TZ</code> environment variable.
+ While an administrator can "do everything in <abbr>UT</abbr>" to
+ get around the problem, doing so is inconvenient and precludes
+ handling daylight saving time shifts - as might be required to
+ limit phone calls to off-peak hours.)
+ </li>
+ <li>
+ POSIX provides no convenient and efficient way to determine
+ the <abbr>UT</abbr> offset and time zone abbreviation of arbitrary
+ timestamps, particularly for <code><abbr>tz</abbr></code> regions
+ that do not fit into the POSIX model.
+ </li>
+ <li>
+ POSIX requires that systems ignore leap seconds.
+ </li>
+ <li>
+ The <code><abbr>tz</abbr></code> code attempts to support all the
+ <code>time_t</code> implementations allowed by POSIX.
+ The <code>time_t</code> type represents a nonnegative count of seconds
+ since 1970-01-01 00:00:00 <abbr>UTC</abbr>, ignoring leap seconds.
+ In practice, <code>time_t</code> is usually a signed 64- or 32-bit
+ integer; 32-bit signed <code>time_t</code> values stop working after
+ 2038-01-19 03:14:07 <abbr>UTC</abbr>, so new implementations these
+ days typically use a signed 64-bit integer.
+ Unsigned 32-bit integers are used on one or two platforms, and 36-bit
+ and 40-bit integers are also used occasionally.
+ Although earlier POSIX versions allowed <code>time_t</code> to be a
+ floating-point type, this was not supported by any practical systems,
+ and POSIX.1-2013 and the <code><abbr>tz</abbr></code> code both
+ require <code>time_t</code> to be an integer type.
+ </li>

+ <p>
+ The <code>TZ</code> environment variable is used in generating
+ the name of a binary file from which time-related information is read
+ (or is interpreted à la POSIX); <code>TZ</code> is no longer
+ constrained to be a three-letter time zone
+ abbreviation followed by a number of hours and an optional three-letter
+ daylight time zone abbreviation.
+ The daylight saving time rules to be used for a
+ particular <code><abbr>tz</abbr></code> region are encoded in the
+ binary file; the format of the file
+ allows U.S., Australian, and other rules to be encoded, and
+ allows for situations where more than two time zone
+ abbreviations are used.
+ </p>
+ <p>
+ It was recognized that allowing the <code>TZ</code> environment
+ variable to take on values such as '<code>America/New_York</code>'
+ might cause "old" programs (that expect <code>TZ</code> to have a
+ certain form) to operate incorrectly; consideration was given to using
+ some other environment variable (for example, <code>TIMEZONE</code>)
+ to hold the string used to generate the binary file's name.
+ In the end, however, it was decided to continue using
+ <code>TZ</code>: it is widely used for time zone purposes;
+ separately maintaining both <code>TZ</code>
+ and <code>TIMEZONE</code> seemed a nuisance; and systems where
+ "new" forms of <code>TZ</code> might cause problems can simply
+ use <code>TZ</code> values such as "<code>EST5EDT</code>" which
+ can be used both by "new" programs (à la POSIX) and "old"
+ programs (as zone names and offsets).

+ if such code is moved to "old" systems that do not

+ (These functions also arrange for local wall clock time to
+ be used if <code>tzset</code> is called – directly or

+title="application programming interface">API</abbr>s</a> that are vestigial:

+not suffice to handle many real-world timestamps.
+Although the <code><abbr>tz</abbr></code> code supports these

+be avoided in portable applications.
+The vestigial <abbr>API</abbr>s are:
+</p>
+<ul>
+ <li>
+ The POSIX <code>tzname</code> variable does not suffice and is no

+ To get a timestamp's time zone abbreviation, consult

+ specification.
+ </li>
+ <li>
+ The POSIX <code>daylight</code> and <code>timezone</code>

+ To get a timestamp's <abbr>UT</abbr> offset, consult
+ the <code>tm_gmtoff</code> member if available; otherwise,

+ <abbr>API</abbr>s.
+ Although it can still be used in arguments to
+ <code>mktime</code> to disambiguate timestamps near
+ a <abbr>DST</abbr> transition when the clock jumps back, this

+ abbreviation, and we refuse to guess.
+ Programs that in the past used the <code>timezone</code> function
+ may now examine <code>localtime(&clock)->tm_zone</code>
+ (if <code>TM_ZONE</code> is defined) or

+<p>
+Some people's work schedules
+use <a href="https://en.wikipedia.org/wiki/Timekeeping on Mars">Mars time</a>.
+Jet Propulsion Laboratory (JPL) coordinators kept Mars time on
+and off during the
+<a href="https://en.wikipedia.org/wiki/Mars_Pathfinder#End_of_mission">Mars
+Pathfinder</a> mission.
+Some of their family members also adapted to Mars time.
+Dozens of special Mars watches were built for JPL workers who kept
+Mars time during the Mars Exploration Rovers mission (2004).
+These timepieces look like normal Seikos and Citizens but use Mars
+seconds rather than terrestrial seconds.
+</p>
+
+<p>
+A Mars solar day is called a "sol" and has a mean period equal to
+about 24 hours 39 minutes 35.244 seconds in terrestrial time.
+It is divided into a conventional 24-hour clock, so each Mars second
+equals about 1.02749125 terrestrial seconds.
+</p>
+
+<p>
+The <a href="https://en.wikipedia.org/wiki/Prime_meridian">prime
+meridian</a> of Mars goes through the center of the crater
+<a href="https://en.wikipedia.org/wiki/Airy-0">Airy-0</a>, named in
+honor of the British astronomer who built the Greenwich telescope that
+defines Earth's prime meridian.
+Mean solar time on the Mars prime meridian is
+called <a href="https://en.wikipedia.org/wiki/Mars_Coordinated_Time">Mars
+Coordinated Time (<abbr>MTC</abbr>)</a>.
+</p>
+
+<p>
+Each landed mission on Mars has adopted a different reference for
+solar time keeping, so there is no real standard for Mars time zones.
+For example, the
+<a href="https://en.wikipedia.org/wiki/Mars_Exploration_Rover">Mars
+Exploration Rover</a> project (2004) defined two time zones "Local
+Solar Time A" and "Local Solar Time B" for its two missions, each zone
+designed so that its time equals local true solar time at
+approximately the middle of the nominal mission.
+Such a "time zone" is not particularly suited for any application
+other than the mission itself.
+</p>
+
+<p>
+Many calendars have been proposed for Mars, but none have achieved
+wide acceptance.
+Astronomers often use Mars Sol Date (<abbr>MSD</abbr>) which is a
+sequential count of Mars solar days elapsed since about 1873-12-29
+12:00 <abbr>GMT</abbr>.
+</p>
+
+<p>
+In our solar system, Mars is the planet with time and calendar most
+like Earth's.
+On other planets, Sun-based time and calendars would work quite
+differently.
+For example, although Mercury's
+<a href="https://en.wikipedia.org/wiki/Rotation_period">sidereal
+rotation period</a> is 58.646 Earth days, Mercury revolves around the
+Sun so rapidly that an observer on Mercury's equator would see a
+sunrise only every 175.97 Earth days, i.e., a Mercury year is 0.5 of a
+Mercury day.
+Venus is more complicated, partly because its rotation is slightly
+<a href="https://en.wikipedia.org/wiki/Retrograde_motion">retrograde</a>:
+its year is 1.92 of its days.
+Gas giants like Jupiter are trickier still, as their polar and
+equatorial regions rotate at different rates, so that the length of a
+day depends on latitude.
+This effect is most pronounced on Neptune, where the day is about 12
+hours at the poles and 18 hours at the equator.
+</p>
+
+<p>
+Although the <code><abbr>tz</abbr></code> database does not support
+time on other planets, it is documented here in the hopes that support
+will be added eventually.
