-# From Lee Hotz (2001-03-08):
-# I queried the folks at Columbia who spent the summer at Vostok and this is

-# "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.
