From Tim Parenti (2024-07-01):
For timestamps before Mozambique's independence, see commentary for
Europe/Lisbon.

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.
