      9 # From Paul Eggert (2013-02-21):
     10 #
     11 # A good source for time zone historical data outside the U.S. is
     12 # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
     13 # San Diego: ACS Publications, Inc. (2003).
     14 #
     15 # Gwillim Law writes that a good source
     16 # for recent time zone data is the International Air Transport
     17 # Association's Standard Schedules Information Manual (IATA SSIM),
     18 # published semiannually.  Law sent in several helpful summaries
     19 # of the IATA's data after 1990.
     20 #
     21 # Except where otherwise noted, Shanks & Pottenger is the source for
     22 # entries through 1990, and IATA SSIM is the source for entries afterwards.
     23 #
     24 # Another source occasionally used is Edward W. Whitman, World Time Differences,
     25 # Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
     26 # I found in the UCLA library.
     27 #
     28 # For data circa 1899, a common source is:
     29 # Milne J. Civil time. Geogr J. 1899 Feb;13(2):173-94.
     30 # http://www.jstor.org/stable/1774359
     31 #
     32 # A reliable and entertaining source about time zones is
     33 # Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
     34 #
     35 # Previous editions of this database used WAT, CAT, SAT, and EAT
     36 # for +0:00 through +3:00, respectively,
     37 # but Mark R V Murray reports that
     38 # 'SAST' is the official abbreviation for +2:00 in the country of South Africa,
     39 # 'CAT' is commonly used for +2:00 in countries north of South Africa, and
     40 # 'WAT' is probably the best name for +1:00, as the common phrase for
     41 # the area that includes Nigeria is "West Africa".
     42 # He has heard of "Western Sahara Time" for +0:00 but can find no reference.
     43 #
     44 # To make things confusing, 'WAT' seems to have been used for -1:00 long ago;
     45 # I'd guess that this was because people needed _some_ name for -1:00,
     46 # and at the time, far west Africa was the only major land area in -1:00.
     47 # This usage is now obsolete, as the last use of -1:00 on the African
     48 # mainland seems to have been 1976 in Western Sahara.
     49 #
     50 # To summarize, the following abbreviations seem to have some currency:
     51 #	-1:00	WAT	West Africa Time (no longer used)
     52 #	 0:00	GMT	Greenwich Mean Time
     53 #	 2:00	CAT	Central Africa Time
     54 #	 2:00	SAST	South Africa Standard Time
     55 # and Murray suggests the following abbreviation:
     56 #	 1:00	WAT	West Africa Time
     57 # I realize that this leads to 'WAT' being used for both -1:00 and 1:00
     58 # for times before 1976, but this is the best I can think of
     59 # until we get more information.
     60 #
     61 # I invented the following abbreviations; corrections are welcome!
     62 #	 2:00	WAST	West Africa Summer Time
     63 #	 2:30	BEAT	British East Africa Time (no longer used)
     64 #	 2:45	BEAUT	British East Africa Unified Time (no longer used)
     65 #	 3:00	CAST	Central Africa Summer Time (no longer used)
     66 #	 3:00	SAST	South Africa Summer Time (no longer used)
     67 #	 3:00	EAT	East Africa Time
     68 #	 4:00	EAST	East Africa Summer Time (no longer used)

    237 # From Abdelrahman Hassan (2007-09-06):
    238 # Due to the Hijri (lunar Islamic calendar) year being 11 days shorter
    239 # than the year of the Gregorian calendar, Ramadan shifts earlier each
    240 # year. This year it will be observed September 13 (September is quite
    241 # hot in Egypt), and the idea is to make fasting easier for workers by
    242 # shifting business hours one hour out of daytime heat. Consequently,
    243 # unless discontinued, next DST may end Thursday 28 August 2008.

    321 
    322 # From Paul Eggert (2014-06-04):
    323 # Sarah El Deeb and Lee Keath of AP report that the Egyptian government says
    324 # the change is because of blackouts in Cairo, even though Ahram Online (cited
    325 # above) says DST had no affect on electricity consumption.  There is
    326 # no information about when DST will end this fall.  See:

    328 #
    329 # For now, guess that later spring and fall transitions will use
    330 # 2010's rules, and guess that Egypt will switch to standard time at
    331 # 24:00 the last Thursday before Ramadan, and back to DST at 00:00 the
    332 # first Friday after Ramadan.  To implement this,
    333 # transition dates for 2015 through 2037 were determined by running
    334 # the following program under GNU Emacs 24.3, with the results integrated
    335 # by hand into the table below.  Ramadan again intrudes on the guessed
    336 # DST starting in 2038, but that's beyond our somewhat-arbitrary cutoff.

    572 # A little strange though, since the article says that they moved the date

    667 # (and republished here: <http://www.actu.ma/heure-dete-comment_i127896_0.html>)
    668 # the changes occur at midnight:
    669 #
    670 # Saturday night May 31st at midnight (which in French is to be
    671 # interpreted as the night between Saturday and Sunday)
    672 # Sunday night the 28th at midnight
    673 #
    674 # Seeing that the 28th is Monday, I am guessing that she intends to say
    675 # the midnight of the 28th which is the midnight between Sunday and
    676 # Monday, which jives with other sources that say that it's inclusive
    677 # June 1st to Sept 27th.
    678 #
    679 # The decision was taken by decree *2-08-224 *but I can't find the decree
    680 # published on the web.
    681 #
    682 # It's also confirmed here:
