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

203# From Paul-Inge Flakstad (2014-03-10):
204# I recently had a long dialog about this with the developer of timegenie.com.
205# In the absence of specific dates, he decided to choose some likely ones:
206#   GMT +1 - From March 1 to the last Sunday in March
207#   GMT +2 - From the last Sunday in March until the last Sunday in October
208#   GMT +1 - From the last Sunday in October until November 7
209#   GMT +0 - From November 7 until March 1
210# The dates for switching to and from UTC+0 will probably not be absolutely

213# From Paul Eggert (2014-03-21):
214# The CET-switching Troll rules require zic from tz 2014b or later, so as

244# From Craig Mundell (1994-12-15):
245# http://quest.arc.nasa.gov/antarctica/QA/computers/Directions,Time,ZIP
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 Antarctic 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 +06.

318# as supplies for the station were coming from McMurdo Sound,

320# at that time (1957).  (Source: Siple's book 90 Degrees South.)

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