hanges affecting future time stamps
The Mexican state of Quintana Roo, represented by America/Cancun,
will shift from Central Time with DST to Eastern Time without DST
on 2015-02-01 at 02:00. (Thanks to Steffen Thorsen and Gwillim Law.)
Chile will not change clocks in April or thereafter; its new standard time
will be its old daylight saving time. This affects America/Santiago,
Pacific/Easter, and Antarctica/Palmer. (Thanks to Juan Correa.)
New leap second 2015-06-30 23:59:60 UTC as per IERS Bulletin C 49.
(Thanks to Tim Parenti.)
Changes affecting past time stamps
Iceland observed DST in 1919 and 1921, and its 1939 fallback
transition was Oct. 29, not Nov. 29. Remove incorrect data from
Shanks about time in Iceland between 1837 and 1908.
Some more zones have been turned into links, when they differed
from existing zones only for older time stamps. As usual,
these changes affect UTC offsets in pre-1970 time stamps only.
Their old contents have been moved to the 'backzone' file.
The affected zones are: Asia/Aden, Asia/Bahrain, Asia/Kuwait,
and Asia/Muscat.

#

# 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 UTC+6.

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

# McMurdo Station, Ross Island, since 1955-12

# Amundsen-Scott South Pole Station, continuously occupied since 1956-11-20

#
|
|
# From Chris Carrier (1996-06-27):
|
|
# Siple, the first commander of the South Pole station,
|
|
# stated that he would have liked to have kept GMT at the station,
|
|
# 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.)

|
|
# 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!!
