# From Paul Eggert (2020-04-14):
# From Milamber (2020-05-31)
# In Morocco (where I live), the end of Ramadan (Arabic month) is followed by
# the Eid al-Fitr, and concretely it's 1 or 2 day offs for the people (with
# traditional visiting of family, big lunches/dinners, etc.). So for this
# year the astronomical calculations don't include the following 2 days off in
# the calc. These 2 days fall in a Sunday/Monday, so it's not acceptable by
# people to have a time shift during these 2 days off. Perhaps you can modify
# the (predicted) rules for next years: if the end of Ramadan is a (probable)
# Friday or Saturday (and so the 2 days off are on a weekend), the next time
# shift will be the next weekend.
#
# From Paul Eggert (2020-05-31):
# For now, guess that in the future Morocco will fall back at 03:00
# the last Sunday before Ramadan, and spring forward at 02:00 the
# first Sunday after the day after Ramadan. To implement this,
# transition dates for 2021 through 2087 were determined by running
# the following program under GNU Emacs 26.3.

# From Michael Deckers (2020-06-11):
# the law of 1891 <https://gallica.bnf.fr/ark:/12148/bpt6k64415343.texteImage>
# was published on 1891-03-15, so it could only take force on 1891-03-16.
# From Michael Deckers (2020-06-10):
# Le Gaulois, 1911-03-11, page 1/6, online at
# https://www.retronews.fr/societe/echo-de-presse/2018/01/29/1911-change-lheure-de-paris
# ... [ Instantly, all pressure driven clock dials halted... Nine minutes and
# twenty-one seconds later the hands resumed their circular motion. ]
# There are also precise reports about how the change was prepared in train
# stations: all the publicly visible clocks stopped at midnight railway time
# (or were covered), only the chief of service had a watch, labeled
# "Heure ancienne", that he kept running until it reached 00:04:21, when
# he announced "Heure nouvelle". See the "Le Petit Journal 1911-03-11".
# https://gallica.bnf.fr/ark:/12148/bpt6k6192911/f1.item.zoom
#
# From Michael Deckers (2020-06-12):
# That "all French clocks stopped" for 00:09:21 is a misreading of French
# newspapers; this sort of adjustment applies only to certain
# remote-controlled clocks ("pendules pneumatiques", of which there existed
# perhaps a dozen in Paris, and which simply could not be set back remotely),
# but not to all the clocks in all French towns and villages. For instance,
# the following story in the "Courrier de Saône-et-Loire" 1911-03-11, page 2:
# only works if legal time was stepped back (was not monotone): ...
# [One can observe that children who had been born at midnight less 5
# minutes and who had died at midnight of the old time, would turn out to
# be dead before being born, time having been set back and having
# suppressed 9 minutes and 25 seconds of their existence, that is, more
# than they could spend.]
#
# From Paul Eggert (2020-06-12):
# French time in railway stations was legally five minutes behind civil time,
# which explains why railway "old time" ran to 00:04:21 instead of to 00:09:21.
# The law's text (which Michael Deckers noted is at
# <https://gallica.bnf.fr/ark:/12148/bpt6k2022333z/f2>) says only that
# at 1911-03-11 00:00 legal time was that of Paris mean time delayed by
# nine minutes and twenty-one seconds, and does not say how the
# transition from Paris mean time was to occur.
#
# tzdb has no way to represent stopped clocks. As the railway practice
# was to keep a watch running on "old time" to decide when to restart
# the other clocks, this could be modeled as a transition for "old time" at
# 00:09:21. However, since the law was ambiguous and clocks outside railway
# stations were probably done haphazardly with the popular impression being
# that the transition was done at 00:00 "old time", simply leave the time
# blank; this causes zic to default to 00:00 "old time" which is good enough.
# Do something similar for the 1891-03-16 transition. There are similar
# problems in Algiers, Monaco and Tunis.
#
# Shank & Pottenger seem to use '24:00' ambiguously; resolve it with Whitman.
