+# From Arthur David Olson (1992-03-08):
# Given the above, what's chosen for year-round use is:
# CST for any place operating at a GMTOFF of 9:30
# WST for any place operating at a GMTOFF of 8:00
# EST for any place operating at a GMTOFF of 10:00
+# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
+# versus "AEST" etc.:
+#
+# I see the following points of dispute:
+#
+# * How important are unique time zone abbreviations?
+#
+# Here I tend to agree with the point (most recently made by Chris
+# Newman) that unique abbreviations should not be essential for proper
+# operation of software. We have other instances of ambiguity
+# (e.g. "IST" denoting both "Israel Standard Time" and "Indian
+# Standard Time"), and they are not likely to go away any time soon.
+# In the old days, some software mistakenly relied on unique
+# abbreviations, but this is becoming less true with time, and I don't
+# think it's that important to cater to such software these days.
+#
+# On the other hand, there is another motivation for unambiguous
+# abbreviations: it cuts down on human confusion. This is
+# particularly true for Australia, where "EST" can mean one thing for
+# time T and a different thing for time T plus 1 second.
+#
+# * Does the relevant legislation indicate which abbreviations should be used?
+#
+# Here I tend to think that things are a mess, just as they are in
+# many other countries. We Americans are currently disagreeing about
+# which abbreviation to use for the newly legislated Chamorro Standard
+# Time, for example.
+#
+# Personally, I would prefer to use common practice; I would like to
+# refer to legislation only for examples of common practice, or as a
+# tiebreaker.
+#
+# * Do Australians more often use "Eastern Daylight Time" or "Eastern
+# Summer Time"? Do they typically prefix the time zone names with
+# the word "Australian"?
+#
+# My own impression is that both "Daylight Time" and "Summer Time" are
+# common and are widely understood, but that "Summer Time" is more
+# popular; and that the leading "A" is also common but is omitted more

+# (19 minutes 32.13 seconds ahead of GMT). This had already been the
+# common practice (except for the railways) for many decades but it was

+# On 1937-07-01 this was changed to 20 minutes (exactly) ahead of GMT and

+# (2001-04-08):

# Svalbard & Jan Mayen
+
+# From Steffen Thorsen (2001-05-01):
+# Although I could not find it explicitly, it seems that Jan Mayen and
+# Svalbard have been using the same time as Norway at least since the
+# time they were declared as parts of Norway. Svalbard was declared
+# as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan
+# Mayen by law of 1930-02-27 no 2, section 2. (From
+# http://www.lovdata.no/all/nl-19250717-011.html and
+# http://www.lovdata.no/all/nl-19300227-002.html). The law/regulation
+# for normal/standard time in Norway is from 1894-06-29 no 1 (came
+# into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a
+# part of this law since 1925/1930. (From
+# http://www.lovdata.no/all/nl-18940629-001.html ) I have not been
+# able to find if Jan Mayen used a different time zone (e.g. -0100)
+# before 1930. Jan Mayen has only been "inhabitated" since 1921 by
+# Norwegian meteorologists and maybe used the same time as Norway ever
+# since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since
+# before 1895, and therefore probably changed the local time somewhere
+# between 1895 and 1925 (inclusive).
+
+# From Paul Eggert (2001-05-01):
+#
+# Actually, Jan Mayen was never occupied by Germany during World War II,
+# so it must have diverged from Oslo time during the war, as Olso was
+# keeping Berlin time.
+#
+# <http://home.no.net/janmayen/history.htm> says that the meteorologists
+# burned down their station in 1940 and left the island, but returned in
+# 1941 with a small Norwegian garrison and continued operations despite
+# frequent air ttacks from Germans. In 1943 the Americans established a
+# radiolocating station on the island, called "Atlantic City". Possibly
+# the UTC offset changed during the war, but I think it unlikely that
+# Jan Mayen used German daylight-saving rules.
+#
+# Svalbard is more complicated, as it was raided in August 1941 by an
+# Allied party that evacuated the civilian population to England (says
+# <http://www.bartleby.com/65/sv/Svalbard.html>). The Svalbard FAQ
+# <http://www.svalbard.com/SvalbardFAQ.html> says that the Germans were
+# expelled on 1942-05-14. However, small parties of Germans did return,
+# and according to Wilhelm Dege's book "War North of 80" (1954)
+# <http://www.utpress.utoronto.ca/publishing/rights/dege_warnorthof80.htm>
+# the German armed forces at the Svalbard weather station code-named
+# Haudegen did not surrender to the Allies until September 1945.
+#
+# All these events predate our cutoff date of 1970. Unless we can
+# come up with more definitive info about the timekeeping during the
+# war years it's probably best just do do the following for now:

+# The law "Svensk forfattningssamling 1878, no 14" about standard time in 1879:
+# From the beginning of 1879 (that is 01-01 00:00) the time for all
+# places in the country is "the mean solar time for the meridian at
+# three degrees, or twelve minutes of time, to the west of the
+# meridian of the Observatory of Stockholm". The law is dated 1878-05-31.
+#
+# The observatory at that time had the meridian 18 degrees 03' 30"
+# eastern longitude = 01:12:14 in time. Less 12 minutes gives the
+# national standard time as 01:00:14 ahead of GMT....
+#
+# About the beginning of CET in Sweden. The lawtext ("Svensk
+# forfattningssamling 1899, no 44") states, that "from the beginning
+# of 1900... ... the same as the mean solar time for the meridian at
+# the distance of one hour of time from the meridian of the English
+# observatory at Greenwich, or at 12 minutes 14 seconds to the west
+# from the meridian of the Observatory of Stockholm". The law is dated
+# 1899-06-16. In short: At 1900-01-01 00:00:00 the new standard time
+# in Sweden is 01:00:00 ahead of GMT.
+#
+# 1916: The lawtext ("Svensk forfattningssamling 1916, no 124") states
+# that "1916-05-15 is considered to begin one hour earlier". It is
+# pretty obvious that at 05-14 23:00 the clocks are set to 05-15 00:00....
+# Further the law says, that "1916-09-30 is considered to end one hour later".
