Hi, tz emailing list I have stumbled over a peculiarity in the historic data about Nigeria, the africa file contains: Zone Africa/Niamey 0:08:28 - LMT 1912 -1:00 - WAT 1934 Feb 26 0:00 - GMT 1960 1:00 - WAT Since the timezone abbreviation 'WAT' is the same seemingly for both GMT-1 and GMT+1, my suspicion is that it should rather be Zone Africa/Niamey 0:08:28 - LMT 1912 1:00 - WAT 1934 Feb 26 0:00 - GMT 1960 1:00 - WAT which would make more sense from the lunar mean time value ... As a side-question, I'm trying to determine a meaningful area for the timezones Atikokan and Nipigon, it seems to me that they would be small, like a US county for instance, but I can't find anything about it. It seems they most be within the larger areas Rainy River district and Thunder Bay district, but how would it look on a map? Regards, Jesper
