# From Steffen Thorsen (2008-08-27):
# Morocco will change the clocks back on the midnight between August 31

+# From Steffen Thorsen (2013-09-28):
+# Morocco extends DST by one month, on very short notice, just 1 day
+# before it was going to end. There is a new decree (2.13.781) for
+# this, where DST from now on goes from last Sunday of March at 02:00
+# to last Sunday of October at 03:00, similar to EU rules. Official
+# source (French):
+# http://www.maroc.gov.ma/fr/actualites/lhoraire-dete-gmt1-maintenu-jusquau-27-octobre-2013
+# Another source (specifying the time for start and end in the decree):
+# http://www.lemag.ma/Heure-d-ete-au-Maroc-jusqu-au-27-octobre_a75620.html
+
+# From Paul Eggert (2013-10-03):
# To estimate what the Moroccan government will do in future years,
-# transition dates for 2014 through 2021 were determined by running
+# transition dates for 2014 through 2038 were determined by running
# the following program under GNU Emacs 24.3:
#
# (let ((islamic-year 1435))
-# (while (< islamic-year 1444)
+# (while (< islamic-year 1461)
# (let ((a
# (calendar-gregorian-from-absolute
# (calendar-islamic-to-absolute (list 9 1 islamic-year))))
# (car (cdr (cdr b))) (calendar-month-name (car b) t) (car (cdr b)))))
# (setq islamic-year (+ 1 islamic-year))))
#
-# with the results hand-edited for 2020-2022, when the normal spring-forward
-# date falls during the estimated Ramadan.
-#
-# From 2023 through 2038 Ramadan is not predicted to overlap with
-# daylight saving time. Starting in 2039 there will be overlap again,
-# but 32-bit time_t values roll around in 2038 so for now do not worry
-# about dates after 2038.
+# with spring-forward transitions removed for 2023-2025, when the
+# normal spring-forward date falls during the estimated Ramadan; with
+# all transitions removed for 2026-2035, where the estimated Ramadan
+# falls entirely outside daylight-saving time; and with fall-back
+# transitions removed for 2036-2037, where the normal fall-back
+# date falls during the estimated Ramadan. Normally, the table would
+# stop after 2037 because 32-bit time_t values roll around early in 2038,
+# but that would imply a prediction of perpetual DST after March 2038
+# due to the year-2037 glitches. So, this table instead stops after
+# 2038, the first non-glitchy year after the 32-bit rollover.
+# An advantage of stopping after 2038 is that it lets zic guess
+# TZ='WET0WEST,M3.5.0,M10.5.0/3' for time stamps far in the future.
