#
# From Paul Eggert (2017-12-07):
# The 1996 anonymous contributor's goal was to determine the correct
# abbreviation for summer time in Dublin and so the contributor
# focused on the "IST", not on the "Irish Summer Time". Though the
# "IST" was correct, the "Irish Summer Time" appears to have been an
# error, as Ireland's Standard Time (Amendment) Act, 1971 states that
# standard time in Ireland remains at UT +01 and is observed in
# summer, and that Greenwich mean time is observed in winter. (Thanks
# to Derick Rethans for pointing out the error.) That is, when
# Ireland amended the 1968 act that established UT +01 as Irish
# Standard Time, it left standard time unchanged and established GMT
# as a negative daylight saving time in winter. So, in this database
# IST stands for Irish Summer Time for timestamps before 1968, and for
# Irish Standard Time after that. See:

# Whitman says Dublin Mean Time was -0:25:21, which is more precise than

# The abbreviation DMT stood for "Dublin Mean Time" or "Dunsink Mean Time";

# Whitman says Dublin/Dunsink Mean Time was UT-00:25:21, which agrees

# Observatory; see Malone D. Dunsink and timekeeping. 2016-01-24.
# <https://www.maths.tcd.ie/~dwmalone/time/dunsink.html>. Malone
# writes that the Nautical Almanac listed UT-00:25:22 until 1896, when
# it moved to UT-00:25:21.1 (I confirmed that the 1893 edition used
# the former and the 1896 edition used the latter). Evidently the

# UT-00:25:22 and cites the International Telegraph Bureau. As it is
# not clear that there was any practical significance to the change

#
# From Paul Eggert (2017-12-07):
# The 1996 anonymous contributor's goal was to determine the correct
# abbreviation for summer time in Dublin and so the contributor
# focused on the "IST", not on the "Irish Summer Time". Though the
# "IST" was correct, the "Irish Summer Time" appears to have been an
# error, as Ireland's Standard Time (Amendment) Act, 1971 states that
# standard time in Ireland remains at UT +01 and is observed in
# summer, and that Greenwich mean time is observed in winter. (Thanks
# to Derick Rethans for pointing out the error.) That is, when
# Ireland amended the 1968 act that established UT +01 as Irish
# Standard Time, it left standard time unchanged and established GMT
# as a negative daylight saving time in winter. So, in this database
# IST stands for Irish Summer Time for timestamps before 1968, and for
# Irish Standard Time after that. See:
