244# <a href="http://quest.arc.nasa.gov/antarctica/QA/computers/Directions,Time,ZIP">
245# From Craig Mundell (1994-12-15)</a>:
246# Vostok, which is one of the Russian stations, is set on the same
247# time as Moscow, Russia.
248#
249# From Lee Hotz (2001-03-08):
250# I queried the folks at Columbia who spent the summer at Vostok and this is
251# what they had to say about time there:
252# ``in the US Camp (East Camp) we have been on New Zealand (McMurdo)
253# time, which is 12 hours ahead of GMT. The Russian Station Vostok was
254# 6 hours behind that (although only 2 miles away, i.e. 6 hours ahead
255# of GMT). This is a time zone I think two hours east of Moscow. The
256# natural time zone is in between the two: 8 hours ahead of GMT.''
257#
258# From Paul Eggert (2001-05-04):
259# This seems to be hopelessly confusing, so I asked Lee Hotz about it
260# in person.  He said that some Antartic locations set their local
261# time so that noon is the warmest part of the day, and that this
262# changes during the year and does not necessarily correspond to mean
263# solar noon.  So the Vostok time might have been whatever the clocks
264# happened to be during their visit.  So we still don't really know what time
265# it is at Vostok.  But we'll guess UTC+6.

336# as supplies for the station were coming from McMurdo Sound,
337# which was on GMT+12 because New Zealand was on GMT+12 all year
338# at that time (1957).  (Source: Siple's book 90 degrees SOUTH.)

342# (1995-11-13 16:24:56 +1300, no longer available):
343# We use the same time as McMurdo does.
344# And they use the same time as Christchurch, NZ does....
345# One last quirk about South Pole time.
346# All the electric clocks are usually wrong.
347# Something about the generators running at 60.1hertz or something
348# makes all of the clocks run fast.  So every couple of days,
349# we have to go around and set them back 5 minutes or so.
350# Maybe if we let them run fast all of the time, we'd get to leave here sooner!!
