Paul, The International Atlas says that the city and country have observed a time zone of -1 (Central Europe Time) since 1960. Before that the time zone was 0 (UT). The Wikipedia article on Niamey says that the time zone name is WAT = UTC+1. The article on Switzerland says that its time zone name is CET = UTC+1. The PC Atlas uses WAT for UTC-1, which was in effect in Niger for 1912 to 1934. (Pottenger) AstrolDeluxe displays West Central Africa Time (WCAT) = -1. Perhaps a different term (I propose WCAT), would straighten out the ambiguity and provide a more appropriate term for this obsolete zone.

I believe I have the latest - please check Africa file - it appears to have a minus sign in front of the Feb 1934 date.
Zone Africa/Niamey 0:08:28 - LMT 1912 -1:00 - WAT 1934 Feb 26
That minus sign is also in our source, namely Shanks & Pottenger. Quite possibly it's a typo (it wouldn't be the first time), but it'd be nice to have a source for any fix.
