+#
+# From Paul Eggert (2024-05-24):
+# The London Gazette, 1903-04-03, page 2245, says that
+# as of 1903-03-03 a time ball at the port of Lourenço Marques
+# (as Maputo was then called) was dropped daily at 13:00:00 LMT,
+# corresponding to 22:49:41.7 GMT, so local time was +02:10:18.3.
+# Conversely, the newspaper South Africa, 1909-02-09, page 321,
+# says the port had just installed an apparatus that communicated
+# "from the controlling clock in the new Observatory at Reuben Point ...
+# exact mean South African time, i.e., 30 deg., or 2 hours East of Greenwich".
+# Although Shanks gives 1903-03-01 for the transition to CAT,
+# evidently the port transitioned to CAT after 1903-03-03 but before
+# the Portuguese legal transition of 1912-01-01 (see Europe/Lisbon commentary).
+# For lack of better info, list 1909 as the transition date.
