128# From Steffen Thorsen (2010-03-10):
129# We got these changes from the Australian Antarctic Division:
130# - Macquarie Island will stay on UTC+11 for winter and therefore not
131# switch back from daylight savings time when other parts of Australia do
132# on 4 April.
133#
134# - Casey station reverted to its normal time of UTC+8 on 5 March 2010.
135# The change to UTC+11 is being considered as a regular summer thing but
136# has not been decided yet.
137#
138# - Davis station will revert to its normal time of UTC+7 at 10 March 2010
139# 20:00 UTC.
140#
141# - Mawson station stays on UTC+5.
142#
143# In addition to the Rule changes for Casey/Davis, it means that Macquarie
144# will no longer be like Hobart and will have to have its own Zone created.

307# <a href="http://quest.arc.nasa.gov/antarctica/QA/computers/Directions,Time,ZIP">
308# From Craig Mundell (1994-12-15)</a>:
309# Vostok, which is one of the Russian stations, is set on the same
310# time as Moscow, Russia.
311#
312# From Lee Hotz (2001-03-08):
313# I queried the folks at Columbia who spent the summer at Vostok and this is
314# what they had to say about time there:
315# ``in the US Camp (East Camp) we have been on New Zealand (McMurdo)
316# time, which is 12 hours ahead of GMT. The Russian Station Vostok was
317# 6 hours behind that (although only 2 miles away, i.e. 6 hours ahead
318# of GMT). This is a time zone I think two hours east of Moscow. The
319# natural time zone is in between the two: 8 hours ahead of GMT.''
320#
321# From Paul Eggert (2001-05-04):
322# This seems to be hopelessly confusing, so I asked Lee Hotz about it
323# in person.  He said that some Antartic locations set their local
324# time so that noon is the warmest part of the day, and that this
325# changes during the year and does not necessarily correspond to mean
326# solar noon.  So the Vostok time might have been whatever the clocks
327# happened to be during their visit.  So we still don't really know what time
328# it is at Vostok.  But we'll guess UTC+6.

369#
370# From Ethan Dicks (1996-10-06):
371# It keeps the same time as Punta Arenas, Chile, because, just like us
372# and the South Pole, that's the other end of their supply line....
373# I verified with someone who was there that since 1980,
374# Palmer has followed Chile.  Prior to that, before the Falklands War,
375# Palmer used to be supplied from Argentina.

391# From Paul Eggert (1996-09-03):
392# Normally it wouldn't have a separate entry, since it's like the
393# larger Antarctica/McMurdo since 1970, but it's too famous to omit.

395# From Chris Carrier (1996-06-27):
396# Siple, the first commander of the South Pole station,
397# stated that he would have liked to have kept GMT at the station,
398# but that he found it more convenient to keep GMT+12
399# as supplies for the station were coming from McMurdo Sound,
400# which was on GMT+12 because New Zealand was on GMT+12 all year
401# at that time (1957).  (Source: Siple's book 90 degrees SOUTH.)

403# From Susan Smith
404# http://www.cybertours.com/whs/pole10.html
405# (1995-11-13 16:24:56 +1300, no longer available):
406# We use the same time as McMurdo does.
407# And they use the same time as Christchurch, NZ does....
408# One last quirk about South Pole time.
409# All the electric clocks are usually wrong.
410# Something about the generators running at 60.1hertz or something
411# makes all of the clocks run fast.  So every couple of days,
412# we have to go around and set them back 5 minutes or so.
413# Maybe if we let them run fast all of the time, we'd get to leave here sooner!!
