 255 # From Lee Hotz (2001-03-08):
 256 # I queried the folks at Columbia who spent the summer at Vostok and this is
 257 # what they had to say about time there:
 258 # "in the US Camp (East Camp) we have been on New Zealand (McMurdo)
 259 # time, which is 12 hours ahead of GMT. The Russian Station Vostok was
 260 # 6 hours behind that (although only 2 miles away, i.e. 6 hours ahead
 261 # of GMT). This is a time zone I think two hours east of Moscow. The
 262 # natural time zone is in between the two: 8 hours ahead of GMT."
 263 #
 264 # From Paul Eggert (2001-05-04):
 265 # This seems to be hopelessly confusing, so I asked Lee Hotz about it
 266 # in person.  He said that some Antarctic locations set their local
 267 # time so that noon is the warmest part of the day, and that this
 268 # changes during the year and does not necessarily correspond to mean
 269 # solar noon.  So the Vostok time might have been whatever the clocks
 270 # happened to be during their visit.  So we still don't really know what time
 271 # it is at Vostok.  But we'll guess +06.
