+
+# From Paul Eggert (2017-12-04):
#
-#
-# Whitman says Dublin Mean Time was -0:25:21, which is more precise than
-# Shanks & Pottenger.
-# Perhaps this was Dunsink Observatory Time, as Dunsink Observatory
-# (8 km NW of Dublin's center) seemingly was to Dublin as Greenwich was
-# to London. For example:
+# Dunsink Observatory (8 km NW of Dublin's center) was to Dublin as
+# Greenwich was to London. For example:
#
# "Timeball on the ballast office is down. Dunsink time."
# -- James Joyce, Ulysses
+#
+# The abbreviation DMT stood for "Dublin Mean Time" or "Dunsink Mean Time";
+# this being Ireland, opinions differed.
+#
+# Whitman says Dublin/Dunsink Mean Time was UT-00:25:21, which agrees
+# with measurements of recent visitors to the Meridian Room of Dunsink
+# 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
+# news of this change propagated slowly, as Milne 1899 still lists
+# 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 UT-00:25:22 to UT-00:25:21.1 in civil timekeeping, omit this
+# transition for now and just use the latter value, omitting its
+# fraction since our format cannot represent fractions.
# "Countess Markievicz ... claimed that the [1916] abolition of Dublin Mean Time
# was among various actions undertaken by the 'English' government that
# regulations. I spoke this morning with the Secretary of the Department of
# Justice (tel +353 1 678 9711) who confirmed to me that the correct name is
# "Irish Summer Time", abbreviated to "IST".
+#
+# 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:
