+# lists the Determination of the Time Ordinance, 1919, No. 18,

+# Vanessa Ogle, The Global Transformation of Time, 1870-1950 (2015), p 33,
+# writes "In 1919, the Gold Coast (Ghana as of 1957) made Greenwich
+# time its legal time and simultaneously legalized a summer time of
+# UTC - 00:20 minutes from March to October."; a footnote lists
+# the ordinance as being dated 1919-11-24.
+# The Crown Colonist, Volume 12 (1942), p 176, says "the Government
+# intend advancing Gold Coast time half an hour ahead of G.M.T.
+# The actual date of the alteration has not yet been announced."
+# These sources are incomplete and contradictory.  Possibly what is
+# now Ghana observed different DST regimes in different years.  For
+# lack of better info, use Shanks except treat the minus sign as a

-# From Paul Eggert (2020-10-27):
-# Several of the midnight transitions mentioned above are ambiguous;
-# are they 00:00, 00:00s, 24:00, or 24:00s?  When resolving these ambiguities,
-# try to minimize changes from previous tzdb versions, for lack of better info.
-# Commentary from previous versions is included below, to help explain this.

-# Although L.N. 31/2017 reads that it "shall come into operation at 2:00 a.m.
-# on 11th March 2018", a precise interpretation here poses some problems.  The
-# order states that "the standard time to be observed throughout the Turks and
-# Caicos Islands shall be the same time zone as the Eastern United States of
-# America" and further clarifies "[f]or the avoidance of doubt" that it
-# "applies to the Eastern Standard Time as well as any changes thereto for
-# Daylight Saving Time."  However, as clocks in Turks and Caicos approached
-# 02:00 -04, and thus the declared implementation time, it was still 01:00 EST
-# (-05), as DST in the Eastern US would not start until an hour later.
-#
-# Since it is unlikely that those on the islands switched their clocks twice in
-# the span of an hour, we assume instead that the adoption of EDT actually took
-# effect once clocks in the Eastern US had sprung forward, from 03:00 -04.
-# This discrepancy only affects the time zone abbreviation and DST flag for the
-# intervening hour, not wall clock times, as -04 was maintained throughout.
