Zone Africa/Algiers 0:12:12 - LMT 1891 Mar 15 0:01 0:09:21 - PMT 1911 Mar 11 # Paris Mean Time
Paris longitude is, according to one source, 002 E 20 and Algiers is 003 E 03. To a certain extent one is tempted to interpret PMT as LMT because it is (?) based on politics and not time zone conventions, so the question is was time in Annaba (some 10* East of Algiers) offset by 0:09:21 in 1900, or was it LMT?
Well, time zone conventions are based on politics, so I'm not completely sure what distinction you meant to convey there, but... Until 1891-03-15, Annaba would be following its own LMT, about 40 minutes ahead of Algiers (if your 10 degree comment is correct; it looks more like 5 degrees to me, but I don't have a good map). Then it would join Algiers in following PMT, along with the rest of Algeria: as a French colony, they would be observing France's official time, as referenced through the center of the principal transit instrument in the official observatory in Paris. --Ken Pizzini
