57# - Casey station reverted to its normal time of UTC+8 on 5 March 2010.
58# The change to UTC+11 is being considered as a regular summer thing but

206# From Paul-Inge Flakstad (2014-03-10):
207# I recently had a long dialog about this with the developer of timegenie.com.
208# In the absence of specific dates, he decided to choose some likely ones:
209#   GMT +1 - From March 1 to the last Sunday in March
210#   GMT +2 - From the last Sunday in March until the last Sunday in October
211#   GMT +1 - From the last Sunday in October until November 7

213# The dates for switching to and from UTC+0 will probably not be absolutely

216# From Paul Eggert (2014-03-21):

246# Vostok, since 1957-12-16, temporarily closed 1994-02/1994-11
247# From Craig Mundell (1994-12-15):
248# http://quest.arc.nasa.gov/antarctica/QA/computers/Directions,Time,ZIP
249# Vostok, which is one of the Russian stations, is set on the same
250# time as Moscow, Russia.
251#
252# From Lee Hotz (2001-03-08):
253# I queried the folks at Columbia who spent the summer at Vostok and this is
254# what they had to say about time there:
255# "in the US Camp (East Camp) we have been on New Zealand (McMurdo)
256# time, which is 12 hours ahead of GMT. The Russian Station Vostok was
257# 6 hours behind that (although only 2 miles away, i.e. 6 hours ahead
258# of GMT). This is a time zone I think two hours east of Moscow. The
259# natural time zone is in between the two: 8 hours ahead of GMT."
260#
261# From Paul Eggert (2001-05-04):
262# This seems to be hopelessly confusing, so I asked Lee Hotz about it
263# in person.  He said that some Antarctic locations set their local
264# time so that noon is the warmest part of the day, and that this
265# changes during the year and does not necessarily correspond to mean
266# solar noon.  So the Vostok time might have been whatever the clocks
267# happened to be during their visit.  So we still don't really know what time
268# it is at Vostok.  But we'll guess UTC+6.

320# but that he found it more convenient to keep GMT+12
321# as supplies for the station were coming from McMurdo Sound,
322# which was on GMT+12 because New Zealand was on GMT+12 all year
323# at that time (1957).  (Source: Siple's book 90 Degrees South.)

326# http://www.cybertours.com/whs/pole10.html
327# (1995-11-13 16:24:56 +1300, no longer available):
328# We use the same time as McMurdo does.
329# And they use the same time as Christchurch, NZ does....
330# One last quirk about South Pole time.
331# All the electric clocks are usually wrong.
332# Something about the generators running at 60.1hertz or something
333# makes all of the clocks run fast.  So every couple of days,
334# we have to go around and set them back 5 minutes or so.
335# Maybe if we let them run fast all of the time, we'd get to leave here sooner!!
