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