# Vostok, which is one of the Russian stations, is set on the same
# time as Moscow, Russia.
#
# From Lee Hotz (2001-03-08):
# I queried the folks at Columbia who spent the summer at Vostok and this is
# what they had to say about time there:
# "in the US Camp (East Camp) we have been on New Zealand (McMurdo)
# time, which is 12 hours ahead of GMT. 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. But we'll guess +06.
