The Russian Station Vostok was 255# 6 hours behind that (although only 2 miles away, i.e. 6 hours ahead 256# of GMT). This is a time zone I think two hours east of Moscow. The 257# natural time zone is in between the two: 8 hours ahead of GMT." 258# 259# From Paul Eggert (2001-05-04): 260# This seems to be hopelessly confusing, so I asked Lee Hotz about it 261# in person. He said that some Antarctic locations set their local 262# time so that noon is the warmest part of the day, and that this 263# changes during the year and does not necessarily correspond to mean 264# solar noon. So the Vostok time might have been whatever the clocks 265# happened to be during their visit. So we still don't really know what time 266# it is at Vostok.
