The Russian Station Vostok was 297# 6 hours behind that (although only 2 miles away, i.e. 6 hours ahead 298# of GMT). This is a time zone I think two hours east of Moscow. The 299# natural time zone is in between the two: 8 hours ahead of GMT." 300# 301# From Paul Eggert (2001-05-04): 302# This seems to be hopelessly confusing, so I asked Lee Hotz about it 303# in person. He said that some Antartic locations set their local 304# time so that noon is the warmest part of the day, and that this 305# changes during the year and does not necessarily correspond to mean 306# solar noon. So the Vostok time might have been whatever the clocks 307# happened to be during their visit. So we still don't really know what time 308# it is at Vostok.
