389# From Paul Eggert (2018-01-30):
390# Whitman says DST was observed from 1931 to "the present";
391# Shanks & Pottenger say 1936 to 1942 with 20 minutes of DST,
392# with transitions on 09-01 and 12-31 at 00:00.

396# lists the Determination of the Time Ordinance, 1919, No. 18,
397# "to advance the time observed locally by the space of twenty minutes
398# during the last four months of each year; the object in view being
399# to extend during those months the period of daylight-time available
400# for evening recreation after office hours."
401# Vanessa Ogle, The Global Transformation of Time, 1870-1950 (2015), p 33,
402# writes "In 1919, the Gold Coast (Ghana as of 1957) made Greenwich
403# time its legal time and simultaneously legalized a summer time of
404# UTC - 00:20 minutes from March to October."; a footnote lists
405# the ordinance as being dated 1919-11-24.
406# The Crown Colonist, Volume 12 (1942), p 176, says "the Government
407# intend advancing Gold Coast time half an hour ahead of G.M.T.
408# The actual date of the alteration has not yet been announced."
409# These sources are incomplete and contradictory. Possibly what is
410# now Ghana observed different DST regimes in different years. For
411# lack of better info, use Shanks except treat the minus sign as a
412# typo, and assume DST started in 1920 not 1936.
