News for the tz database
+Release 2015d - 2015-04-24 08:09:46 -0700
+
+ Changes affecting future time stamps
+
+ Egypt will not observe DST in 2015 and will consider canceling it
+ permanently. For now, assume no DST indefinitely.
+ (Thanks to Ahmed Nazmy and Tim Parenti.)
+
+ Changes affecting past time stamps
+
+ America/Whitehorse switched from UTC-9 to UTC-8 on 1967-05-28, not
+ 1966-07-01. Also, Yukon's time zone history is documented better.
+ (Thanks to Brian Inglis and Dennis Ferguson.)
+
+ Change affecting past and future time zone abbreviations
+
+ The abbreviations for Hawaii-Aleutian standard and daylight times
+ have been changed from HAST/HADT to HST/HDT, as per US Government
+ Printing Office style. This affects only America/Adak since 1983,
+ as America/Honolulu was already using the new style.
+
+ Changes affecting code
+
+ zic has some minor performance improvements.
+
+
+Release 2015c - 2015-04-11 08:55:55 -0700
+
+ Changes affecting future time stamps
+
+ Egypt's spring-forward transition is at 24:00 on April's last Thursday,
+ not 00:00 on April's last Friday. 2015's transition will therefore be on
+ Thursday, April 30 at 24:00, not Friday, April 24 at 00:00. Similar fixes
+ apply to 2026, 2037, 2043, etc. (Thanks to Steffen Thorsen.)
+
+ Changes affecting past time stamps
+
+ The following changes affect some pre-1991 Chile-related time stamps
+ in America/Santiago, Antarctica/Palmer, and Pacific/Easter.
+
+ The 1910 transition was January 10, not January 1.
+
+ The 1918 transition was September 10, not September 1.
+
+ The UTC-4 time observed from 1932 to 1942 is now considered to be
+ standard time, not year-round DST.
+
+ Santiago observed DST (UTC-3) from 1946-07-15 through 1946-08-31,
+ then reverted to standard time, then switched its time zone to
+ UTC-5 on 1947-04-01.
+
+ Assume transitions before 1968 were at 00:00, since we have no data
+ saying otherwise.
+
+ The spring 1988 transition was 1988-10-09, not 1988-10-02.
+ The fall 1990 transition was 1990-03-11, not 1990-03-18.
+
+ Assume no UTC offset change for Pacific/Easter on 1890-01-01,
+ and omit all transitions on Pacific/Easter from 1942 through 1946
+ since we have no data suggesting that they existed.
+
+ One more zone has been turned into a link, as it differed
+ from an existing zone only for older time stamps. As usual,
+ this change affects UTC offsets in pre-1970 time stamps only.
+ The zone's old contents have been moved to the 'backzone' file.
+ The affected zone is America/Montreal.
+
+ Changes affecting commentary
+
+ Mention the TZUpdater tool.
+
+ Mention "The Time Now". (Thanks to Brandon Ramsey.)
+
+
+Release 2015b - 2015-03-19 23:28:11 -0700
+
+ Changes affecting future time stamps
+
+ Mongolia will start observing DST again this year, from the last
+ Saturday in March at 02:00 to the last Saturday in September at 00:00.
+ (Thanks to Ganbold Tsagaankhuu.)
+
+ Palestine will start DST on March 28, not March 27. Also,
+ correct the fall 2014 transition from September 26 to October 24.
+ Adjust future predictions accordingly. (Thanks to Steffen Thorsen.)
+
+ Changes affecting past time stamps
+
+ The 1982 zone shift in Pacific/Easter has been corrected, fixing a 2015a
+ regression. (Thanks to Stuart Bishop for reporting the problem.)
+
+ Some more zones have been turned into links, when they differed
+ from existing zones only for older time stamps. As usual,
+ these changes affect UTC offsets in pre-1970 time stamps only.
+ Their old contents have been moved to the 'backzone' file.
+ The affected zones are: America/Antigua, America/Cayman,
+ Pacific/Midway, and Pacific/Saipan.
+
+ Changes affecting time zone abbreviations
+
+ Correct the 1992-2010 DST abbreviation in Volgograd from "MSK" to "MSD".
+ (Thanks to Hank W.)
+
+ Changes affecting code
+
+ Fix integer overflow bug in reference 'mktime' implementation.
+ (Problem reported by Jörg Richter.)
+
+ Allow -Dtime_tz=time_t compilations, and allow -Dtime_tz=... libraries
+ to be used in the same executable as standard-library time_t functions.
+ (Problems reported by Bradley White.)
+
+ Changes affecting commentary
+
+ Cite the recent Mexican decree changing Quintana Roo's time zone.
+ (Thanks to Carlos Raúl Perasso.)
+
+ Likewise for the recent Chilean decree. (Thanks to Eduardo Romero Urra.)
+
+ Update info about Mars time.
+
+
+Release 2015a - 2015-01-29 22:35:20 -0800
+
+ Changes affecting future time stamps
+
+ The Mexican state of Quintana Roo, represented by America/Cancun,
+ will shift from Central Time with DST to Eastern Time without DST
+ on 2015-02-01 at 02:00. (Thanks to Steffen Thorsen and Gwillim Law.)
+
+ Chile will not change clocks in April or thereafter; its new standard time
+ will be its old daylight saving time. This affects America/Santiago,
+ Pacific/Easter, and Antarctica/Palmer. (Thanks to Juan Correa.)
+
+ New leap second 2015-06-30 23:59:60 UTC as per IERS Bulletin C 49.
+ (Thanks to Tim Parenti.)
+
+ Changes affecting past time stamps
+
+ Iceland observed DST in 1919 and 1921, and its 1939 fallback
+ transition was Oct. 29, not Nov. 29. Remove incorrect data from
+ Shanks about time in Iceland between 1837 and 1908.
+
+ Some more zones have been turned into links, when they differed
+ from existing zones only for older time stamps. As usual,
+ these changes affect UTC offsets in pre-1970 time stamps only.
+ Their old contents have been moved to the 'backzone' file.
+ The affected zones are: Asia/Aden, Asia/Bahrain, Asia/Kuwait,
+ and Asia/Muscat.
+
+ Changes affecting code
+
+ tzalloc now scrubs time zone abbreviations compatibly with the way
+ that tzset always has, by replacing invalid bytes with '_' and by
+ shortening too-long abbreviations.
+
+ tzselect ports to POSIX awk implementations, no longer mishandles
+ POSIX TZ settings when GNU awk is used, and reports POSIX TZ
+ settings to the user. (Thanks to Stefan Kuhn.)
+
+ Changes affecting build procedure
+
+ 'make check' now checks for links to links in the data.
+ One such link (for Africa/Asmera) has been fixed.
+ (Thanks to Stephen Colebourne for pointing out the problem.)
+
+ Changes affecting commentary
+
+ The leapseconds file commentary now mentions the expiration date.
+ (Problem reported by Martin Burnicki.)
+
+ Update Mexican Library of Congress URL.
+
+
+Release 2014j - 2014-11-10 17:37:11 -0800
+
+ Changes affecting current and future time stamps
+
+ Turks & Caicos' switch from US eastern time to UTC-4 year-round
+ did not occur on 2014-11-02 at 02:00. It's currently scheduled
+ for 2015-11-01 at 02:00. (Thanks to Chris Walton.)
+
+ Changes affecting past time stamps
+
+ Many pre-1989 time stamps have been corrected for Asia/Seoul and
+ Asia/Pyongyang, based on sources for the Korean-language Wikipedia
+ entry for time in Korea. (Thanks to Sanghyuk Jung.) Also, no
+ longer guess that Pyongyang mimicked Seoul time after World War II,
+ as this is politically implausible.
+
+ Some more zones have been turned into links, when they differed
+ from existing zones only for older time stamps. As usual,
+ these changes affect UTC offsets in pre-1970 time stamps only.
+ Their old contents have been moved to the 'backzone' file.
+ The affected zones are: Africa/Addis_Ababa, Africa/Asmara,
+ Africa/Dar_es_Salaam, Africa/Djibouti, Africa/Kampala,
+ Africa/Mogadishu, Indian/Antananarivo, Indian/Comoro, and
+ Indian/Mayotte.
+
+ Changes affecting commentary
+
+ The commentary is less enthusiastic about Shanks as a source,
+ and is more careful to distinguish UT from UTC.
+
+

+#

+# 1916 to 1919 was -4:42:46.3, the meridian of Chile's National
+# Astronomical Observatory (OAN), then located in what is now
+# Quinta Normal in Santiago. Go with [2], rounding it to -4:42:46.

+# at midnight mainland time, the current common practice. However,
