221# <a href="http://quest.arc.nasa.gov/antarctica/QA/computers/Directions,Time,ZIP">
222# From Craig Mundell (1994-12-15)</a>:
223# Vostok, which is one of the Russian stations, is set on the same
224# time as Moscow, Russia.
225#
226# From Lee Hotz (2001-03-08):
227# I queried the folks at Columbia who spent the summer at Vostok and this is
228# what they had to say about time there:
229# ``in the US Camp (East Camp) we have been on New Zealand (McMurdo)
230# time, which is 12 hours ahead of GMT. The Russian Station Vostok was
231# 6 hours behind that (although only 2 miles away, i.e. 6 hours ahead
232# of GMT). This is a time zone I think two hours east of Moscow. The
233# natural time zone is in between the two: 8 hours ahead of GMT.''
234#
235# From Paul Eggert (2001-05-04):
236# This seems to be hopelessly confusing, so I asked Lee Hotz about it
237# in person.  He said that some Antartic locations set their local
238# time so that noon is the warmest part of the day, and that this
239# changes during the year and does not necessarily correspond to mean
240# solar noon.  So the Vostok time might have been whatever the clocks
241# happened to be during their visit.  So we still don't really know what time
242# it is at Vostok.  But we'll guess UTC+6.

312# but that he found it more convenient to keep GMT+12
313# as supplies for the station were coming from McMurdo Sound,
314# which was on GMT+12 because New Zealand was on GMT+12 all year
315# at that time (1957).  (Source: Siple's book 90 degrees SOUTH.)

319# (1995-11-13 16:24:56 +1300, no longer available):
320# We use the same time as McMurdo does.
321# And they use the same time as Christchurch, NZ does....
322# One last quirk about South Pole time.
323# All the electric clocks are usually wrong.
324# Something about the generators running at 60.1hertz or something
325# makes all of the clocks run fast.  So every couple of days,
326# we have to go around and set them back 5 minutes or so.
327# Maybe if we let them run fast all of the time, we'd get to leave here sooner!!
