# I recently had a long dialog about this with the developer of timegenie.com.

#   GMT +2 - From the last Sunday in March until the last Sunday in October

#   GMT +1 - From the last Sunday in October until November 7

#   GMT +0 - From November 7 until March 1

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

# correct, but they should be quite close to the actual dates.

#

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

# Vostok, which is one of the Russian stations, is set on the same

# time as Moscow, Russia.

#

# From Lee Hotz (2001-03-08):

# I queried the folks at Columbia who spent the summer at Vostok and this is

# what they had to say about time there:

# "in the US Camp (East Camp) we have been on New Zealand (McMurdo)

# time, which is 12 hours ahead of GMT. The Russian Station Vostok was

# 6 hours behind that (although only 2 miles away, i.e. 6 hours ahead

# of GMT). This is a time zone I think two hours east of Moscow. The

# natural time zone is in between the two: 8 hours ahead of GMT."

#

# From Paul Eggert (2001-05-04):

# This seems to be hopelessly confusing, so I asked Lee Hotz about it

# in person.  He said that some Antarctic locations set their local

# time so that noon is the warmest part of the day, and that this

# changes during the year and does not necessarily correspond to mean

# solar noon.  So the Vostok time might have been whatever the clocks

# happened to be during their visit.  So we still don't really know what time

# it is at Vostok.  But we'll guess +06.

# but that he found it more convenient to keep GMT+12

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

# which was on GMT+12 because New Zealand was on GMT+12 all year

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

# From Susan Smith

# http://www.cybertours.com/whs/pole10.html

# (1995-11-13 16:24:56 +1300, no longer available):

# We use the same time as McMurdo does.

# And they use the same time as Christchurch, NZ does....

# One last quirk about South Pole time.

# All the electric clocks are usually wrong.

# Something about the generators running at 60.1hertz or something

# makes all of the clocks run fast.  So every couple of days,

# we have to go around and set them back 5 minutes or so.

# Maybe if we let them run fast all of the time, we'd get to leave here sooner!!
