# From Paul Eggert (2017-02-20):
#
# Unless otherwise specified, the source for data through 1990 is:
# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
# San Diego: ACS Publications, Inc. (2003).
# Unfortunately this book contains many errors and cites no sources.
#
# Many years ago Gwillim Law wrote that a good source
# for time zone data was the International Air Transport
# Association's Standard Schedules Information Manual (IATA SSIM),
# published semiannually.  Law sent in several helpful summaries
# of the IATA's data after 1990.  Except where otherwise noted,
# IATA SSIM is the source for entries after 1990.
#
# Another source occasionally used is Edward W. Whitman, World Time Differences,
# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
# I found in the UCLA library.
#
# For data circa 1899, a common source is:
# Milne J. Civil time. Geogr J. 1899 Feb;13(2):173-94.
# https://www.jstor.org/stable/1774359
#
# A reliable and entertaining source about time zones is
# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
#
# European-style abbreviations are commonly used along the Mediterranean.
# For sub-Saharan Africa abbreviations were less standardized.
# Previous editions of this database used WAT, CAT, SAT, and EAT
# for UT +00 through +03, respectively,
# but in 1997 Mark R V Murray reported that
# 'SAST' is the official abbreviation for +02 in the country of South Africa,
# 'CAT' is commonly used for +02 in countries north of South Africa, and
# 'WAT' is probably the best name for +01, as the common phrase for
# the area that includes Nigeria is "West Africa".
#
# To summarize, the following abbreviations seemed to have some currency:
#	 +00	GMT	Greenwich Mean Time
#	 +02	CAT	Central Africa Time
#	 +02	SAST	South Africa Standard Time
# and Murray suggested the following abbreviation:
#	 +01	WAT	West Africa Time
# Murray's suggestion seems to have caught on in news reports and the like.
# I vaguely recall 'WAT' also being used for -01 in the past but
# cannot now come up with solid citations.
#
# I invented the following abbreviations; corrections are welcome!
#	 +02	WAST	West Africa Summer Time
#	 +03	CAST	Central Africa Summer Time (no longer used)
#	 +03	SAST	South Africa Summer Time (no longer used)
#	 +03	EAT	East Africa Time
# 'EAT' also seems to have caught on; the others are rare but are paired
# with better-attested non-DST abbreviations.

# From Abdelrahman Hassan (2007-09-06):
# Due to the Hijri (lunar Islamic calendar) year being 11 days shorter
# than the year of the Gregorian calendar, Ramadan shifts earlier each
# year. This year it will be observed September 13 (September is quite
# hot in Egypt), and the idea is to make fasting easier for workers by
# shifting business hours one hour out of daytime heat. Consequently,
# unless discontinued, next DST may end Thursday 28 August 2008.
# From Paul Eggert (2007-08-17):
# For lack of better info, assume the new rule is last Thursday in August.

# From Steffen Thorsen (2008-06-25):
# Mauritius plans to observe DST from 2008-11-01 to 2009-03-31 on a trial
# basis....
# It seems that Mauritius observed daylight saving time from 1982-10-10 to
# 1983-03-20 as well, but that was not successful....

# From Arthur David Olson (2008-06-30):
# The www.timeanddate.com article cited by Steffen Thorsen notes that "A
# final decision has yet to be made on the times that daylight saving
# would begin and end on these dates." As a place holder, use midnight.

# From Paul Eggert (2008-06-30):
# Follow Thorsen on DST in 1982/1983, instead of Shanks & Pottenger.

# From Steffen Thorsen (2008-07-10):
# According to
# http://www.lexpress.mu/display_article.php?news_id=111216
# (in French), Mauritius will start and end their DST a few days earlier
# than previously announced (2008-11-01 to 2009-03-31).  The new start
# date is 2008-10-26 at 02:00 and the new end date is 2009-03-27 (no time
# given, but it is probably at either 2 or 3 wall clock time).
#
# A little strange though, since the article says that they moved the date
# to align itself with Europe and USA which also change time on that date,
# but that means they have not paid attention to what happened in
# USA/Canada last year (DST ends first Sunday in November). I also wonder
# why that they end on a Friday, instead of aligning with Europe which
# changes two days later.

# From Alex Krivenyshev (2008-07-11):
# Seems that English language article "The revival of daylight saving
# time: Energy conservation?"- No. 16578 (07/11/2008) was originally
# published on Monday, June 30, 2008...
#
# I guess that article in French "Le gouvernement avance l'introduction
# de l'heure d'��t��" stating that DST in Mauritius starting on October 26
# and ending on March 27, 2009 is the most recent one....

# Cabinet Decision of July 18th, 2008 states as follows:
#
# 4. ...Cabinet has agreed to the introduction into the National Assembly
# of the Time Bill which provides for the introduction of summer time in
# Mauritius. The summer time period which will be of one hour ahead of
# the standard time, will be aligned with that in Europe and the United
# States of America. It will start at two o'clock in the morning on the
# last Sunday of October and will end at two o'clock in the morning on
# the last Sunday of March the following year. The summer time for the
# year 2008-2009 will, therefore, be effective as from 26 October 2008
# and end on 29 March 2009.

#
# Saturday night May 31st at midnight (which in French is to be
# interpreted as the night between Saturday and Sunday)
# Sunday night the 28th at midnight
#
# Seeing that the 28th is Monday, I am guessing that she intends to say
# the midnight of the 28th which is the midnight between Sunday and
# Monday, which jives with other sources that say that it's inclusive
# June 1st to Sept 27th.
#
# The decision was taken by decree *2-08-224 *but I can't find the decree
# published on the web.

# [The gov.ma announcement] would (probably) make the switch on 2015-07-19 go
# from 03:00 to 04:00 rather than from 02:00 to 03:00, as in the patch....
# I think the patch is correct and the quoted text is wrong; the text in

# with the patch.

# From Paul Eggert (2015-06-08):
# For now, guess that later spring and fall transitions will use 2015's rules,
# and guess that Morocco will switch to standard time at 03:00 the last
# Sunday before Ramadan, and back to DST at 02:00 the first Sunday after
# Ramadan.  To implement this, transition dates for 2016 through 2037 were

# results integrated by hand into the table below.

# From Arthur David Olson (2017-08-09):
# The text of the "Namibia Time Act, 1994" is available online at

# and includes this nugget:
# Notwithstanding the provisions of subsection (2) of section 1, the
# first winter period after the commencement of this Act shall
# commence at OOhOO on Monday 21 March 1994 and shall end at 02h00 on
# Sunday 4 September 1994.

# From Petronella Sibeene (2007-03-30):
# http://allafrica.com/stories/200703300178.html
# While the entire country changes its time, Katima Mulilo and other
# settlements in Caprivi unofficially will not because the sun there
# rises and sets earlier compared to other regions.  Chief of
# Forecasting Riaan van Zyl explained that the far eastern parts of
# the country are close to 40 minutes earlier in sunrise than the rest
# of the country.
#
# From Paul Eggert (2017-02-22):
# Although the Zambezi Region (formerly known as Caprivi) informally
# observes Botswana time, we have no details about historical practice.
# In the meantime people there can use Africa/Gaborone.

# This video is from the government decision:

# From Gwillim Law (2005-04-30):
# My correspondent, Risto Nyk��nen, has alerted me to another adoption of DST,
# this time in Tunisia.  According to Yahoo France News
# <http://fr.news.yahoo.com/050426/5/4dumk.html>, in a story attributed to AP
# and dated 2005-04-26, "Tunisia has decided to advance its official time by
# one hour, starting on Sunday, May 1.  Henceforth, Tunisian time will be
# UTC+2 instead of UTC+1.  The change will take place at 23:00 UTC next
# Saturday."  (My translation)
#
# From Oscar van Vlijmen (2005-05-02):
# La Presse, the first national daily newspaper ...
# http://www.lapresse.tn/archives/archives280405/actualites/lheure.html
# ... DST for 2005: on: Sun May 1 0h standard time, off: Fri Sept. 30,
# 1h standard time.
#
# From Atef Loukil (2006-03-28):
# The daylight saving time will be the same each year:
# Beginning      : the last Sunday of March at 02:00
# Ending         : the last Sunday of October at 03:00 ...
# http://www.tap.info.tn/en/index.php?option=com_content&task=view&id=1188&Itemid=50

# From Steffen Thorsen (2009-03-16):
# According to several news sources, Tunisia will not observe DST this year.
# (Arabic)
# http://www.elbashayer.com/?page=viewn&nid=42546
# https://www.babnet.net/kiwidetail-15295.asp
#
# We have also confirmed this with the US embassy in Tunisia.
# We have a wrap-up about this on the following page:
# https://www.timeanddate.com/news/time/tunisia-cancels-dst-2009.html

# From Alexander Krivenyshev (2009-03-17):
# Here is a link to Tunis Afrique Presse News Agency
#
# Standard time to be kept the whole year long (tap.info.tn):
#
# (in English)
# http://www.tap.info.tn/en/index.php?option=com_content&task=view&id=26813&Itemid=157
#
# (in Arabic)
# http://www.tap.info.tn/ar/index.php?option=com_content&task=view&id=61240&Itemid=1

# From Arthur David Olson (2009-03-18):
# The Tunis Afrique Presse News Agency notice contains this: "This measure is
# due to the fact that the fasting month of Ramadan coincides with the period
# concerned by summer time.  Therefore, the standard time will be kept
# unchanged the whole year long."  So foregoing DST seems to be an exception
# (albeit one that may be repeated in the future).

# From Alexander Krivenyshev (2010-03-27):
# According to some news reports Tunis confirmed not to use DST in 2010
#
# (translation):
# "The Tunisian government has decided to abandon DST, which was scheduled on
# Sunday...
# Tunisian authorities had suspended the DST for the first time last year also
# coincided with the month of Ramadan..."
