+# The text of the Iranian law, in effect since 1925, clearly mentions

+# That cal-persia used Birashk's approximation, which disagrees with the solar

+#
+# From Oscar van Vlijmen (2005-03-30), writing about future
+# discrepancies between cal-persia and the Iranian calendar:
+# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
+# the vernal equinox and that gets so close to 12:00 some local
+# Iranian time that the definition of the correct location needs to be
+# known exactly, amongst other factors. 2157 is even closer:
+# 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give
+# no interpretation problem whatsoever. By the way, another instant
+# in the near future where there will be a discrepancy between
+# arithmetical and astronomical Iranian calendars will be in 2058:
+# vernal equinox on 2058-03-20 09:03:05.9 UT. The Java version of
+# Reingold's/Dershowitz' calculator gives correctly the Gregorian date
+# 2058-03-21 for 1 Farvardin 1437 (astronomical).

-# Minister of Interior Poraz has announced that he will respect the law
-# passed in July 2000 (proposed at the time jointly by himself and
-# then-MK David Azulai [Shas]) fixing the dates for 2000-2004. Hence,
-# the dates for 2003 and 2004 remain unchanged....
-#
-# As far as 2005 and beyond, no dates have been set. However, the
-# minister has mentioned that he wishes to propose to move Israel's
-# timezone in 2005 from GMT+2 to GMT+3 and upon that have DST during
-# the summer months (i.e. GMT+4). However, no legislation in this
-# direction is expected until the latter part of 2004 which is a long
-# time off in terms of Israeli politics.
-
-# (2004-09-20):
-# The latest rumour, however, is that in 2005, when the clock changes to
-# Daylight Saving Time (date as yet unknown), the move will be a two-hour leap
-# forward (from UTC+0200 to UTC+0400) and then, in the fall, the clock will
-# move back only an hour to UTC+0300 thus effectively moving Israel's timezone
-# from UTC+0200 to UTC+0300. However, no actual draft has been put before the
-# Knesset (Israel's Parliament) though the intention is to do so this
-# month [2004-09].
-
-# (2004-09-26):
-# Even though the draft law for the above did pass the Ministerial Committee
-# for Legislative Matters three months ago, it was voted down in today's
-# Cabinet meeting. The current suggestion is to keep the current timezone at
-# UTC+0200 but have an extended period of Daylight Saving Time (UTC+0300) from
-# the beginning of Passover holiday in the spring to after the Tabernacle
-# holiday in the fall (i.e. the dates of which are governed by the Hebrew
-# calendar but this means at least 184 days of DST). However, this is only a
-# suggestion that was raised in today's cabinet meeting and has not yet been
-# drafted.

# mapmakers redrew the IDL following the boundary of Kiribati. Even that line
# has a rather arbitrary nature. The straight-line boundaries between Pacific
# island nations that are shown on many maps are based on an international
-# convention, but are not legally binding national borders.
-#
-# An Anglo-French Conference on Time-Keeping at Sea (June, 1917) agreed that
-# legal time on the high seas would be zone time, i.e., the standard time at
-# the nearest meridian that is a multiple of fifteen degrees. The date is
+# convention, but are not legally binding national borders.... The date is
# governed by the IDL; therefore, even on the high seas, there may be some
# places as late as fourteen hours later than UTC. And, since the IDL is not
# an international standard, there are some places on the high seas where the
# correct date is ambiguous.
+
+# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31):
+# Before 1920, all ships kept local apparent time on the high seas by setting
+# their clocks at night or at the morning sight so that, given the ship's
+# speed and direction, it would be 12 o'clock when the Sun crossed the ship's
+# meridian (12 o'clock = local apparent noon). During 1917, at the
+# Anglo-French Conference on Time-keeping at Sea, it was recommended that all
+# ships, both military and civilian, should adopt hourly standard time zones
+# on the high seas. Whenever a ship was within the territorial waters of any
+# nation it would use that nation's standard time. The captain was permitted
+# to change his ship's clocks at a time of his choice following his ship's
+# entry into another zone time--he often chose midnight. These zones were
+# adopted by all major fleets between 1920 and 1925 but not by many
+# independent merchant ships until World War II.
+
+# From Paul Eggert, using references suggested by Oscar van Vlijmen
+# (2005-03-20):
+#
+# The American Practical Navigator (2002)
+# <http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187>
+# talks only about the 180-degree meridian with respect to ships in
+# international waters; it ignores the international date line.

-# Pam Belluck reported in the New York Times (2001-01-31) that the
-# Indiana Legislature is considering a bill to adopt DST statewide.
-# Her article mentioned Vevay, whose post office observes a different
-# time zone from Danner's Hardware across the street.
+# From Paul Eggert (2005-08-16):
+# http://www.mccsc.edu/time.html says that Indiana will use DST starting 2006.

+# http://dmses.dot.gov/docimages/pdf95/382329_web.pdf
+# From Paul Eggert (2006-01-20):

+# Eastern Time Zone to the Central Time Zone.... The effective date of
+# this rule is 2:OO a.m. EST Sunday, April 2, 2006, which is the
+# changeover date from standard time to Daylight Saving Time."
+# Strictly speaking, this means the affected counties will change their

+# CBC News reported that Ontario and Manitoba have announced plans to
+# follow the US change, and that Nova Scotia is considering it; see
+# <http://www.cbc.ca/news/background/daylightsavingtime/> (2005-10-21).
+# CBC news also reported that Prince Edward Island is the first

+# had agreed; see <http://www.cbc.ca/pei/story/pe_daylight_20051207.html>
+# (2005-12-07).
+#
+# To reflect all this, the Canada and Winn rules have been adjusted to
+# agree with the 2007 US change. This means we assume most of Canada
+# will fall into line. However, Alberta, British Columbia,
+# Newfoundland, Northwest Territories, and Yukon already have separate
+# rules in our database, so for now we'll leave them alone, which
+# means that we currently assume these regions will not change their
+# rules and will disagree with the US starting in 2007. This
+# assumption is probably incorrect, with the possible exception of
+# Newfoundland. We plan to adjust the Edm, Vanc, StJohns, and NT_YK
+# rules as the corresponding provinces make their announcements.

+# assume that it is daylight saving and that they'll switch back on the
+# 3rd Sunday in September.
+#
+# From Gwillim Law (2005-04-21):
+# The Associated Press story on the time change, which can be found at
+# http://www.lapalmainteractivo.com/guias/content/gen/ap/America_Latina/AMC_GEN_NICARAGUA_HORA.html
+# and elsewhere, says (fifth paragraph, translated from Spanish): "The last
+# time that a change of clocks was applied to save energy was in the year 2000
+# during the Arnoldo Aleman administration."...
+# The northamerica file says that Nicaragua has been on UTC-6 continuously
+# since December 1998. I wasn't able to find any details of Nicaraguan time
+# changes in 2000. Perhaps a note could be added to the northamerica file, to
+# the effect that we have indirect evidence that DST was observed in 2000.
+#
+# From Jesper Norgaard Welen (2005-11-02):
+# Nicaragua left DST the 2005-10-02 at 00:00 (local time).
