210# From Paul-Inge Flakstad (2014-03-10):
211# I recently had a long dialog about this with the developer of timegenie.com.

213#   GMT +1 - From March 1 to the last Sunday in March
214#   GMT +2 - From the last Sunday in March until the last Sunday in October
215#   GMT +1 - From the last Sunday in October until November 7
216#   GMT +0 - From November 7 until March 1
217# The dates for switching to and from UTC+0 will probably not be absolutely
218# correct, but they should be quite close to the actual dates.
219#
220# From Paul Eggert (2014-03-21):
221# The CET-switching Troll rules require zic from tz 2014b or later, so as

250# Vostok, since 1957-12-16, temporarily closed 1994-02/1994-11
251# From Craig Mundell (1994-12-15):
252# http://quest.arc.nasa.gov/antarctica/QA/computers/Directions,Time,ZIP
253# Vostok, which is one of the Russian stations, is set on the same
254# time as Moscow, Russia.
255#
256# From Lee Hotz (2001-03-08):
257# I queried the folks at Columbia who spent the summer at Vostok and this is
258# what they had to say about time there:
259# "in the US Camp (East Camp) we have been on New Zealand (McMurdo)
260# time, which is 12 hours ahead of GMT. The Russian Station Vostok was
261# 6 hours behind that (although only 2 miles away, i.e. 6 hours ahead
262# of GMT). This is a time zone I think two hours east of Moscow. The
263# natural time zone is in between the two: 8 hours ahead of GMT."
264#
265# From Paul Eggert (2001-05-04):
266# This seems to be hopelessly confusing, so I asked Lee Hotz about it
267# in person.  He said that some Antarctic locations set their local
268# time so that noon is the warmest part of the day, and that this
269# changes during the year and does not necessarily correspond to mean
270# solar noon.  So the Vostok time might have been whatever the clocks
271# happened to be during their visit.  So we still don't really know what time
272# it is at Vostok.  But we'll guess +06.

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

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

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