CURRENT ftp://ftp.iana.org/tz/code/Theory says "Within a file name component, use only ASCII letters, `.', `-' and `_'." In ftp://ftp.iana.org/tz/data/zone.tab I found none having "." I found three having "-": America/Blanc-Sablon Africa/Porto-Novo America/Port-au-Prince PROPOSED Change ftp://ftp.iana.org/tz/code/Theory "Within a file name component, use only ASCII letters and `_'." REASONING @"." "." is not used, document current usage. Reduce number of possible variations. @"-" Reduce number of possible variations. Avoid discussions about names as happened with the zone proposal for the Crozet Islands "Alfred-Faure" vs "Alfred Faure". @both Some environments don't allow "/". Since "/" is part of the zone name, a replacement may be needed. If "." and "-" are not allowed for zone names anymore, then they can be used for replacing "/". -- Tobias Conradi Rheinsberger Str. 18 10115 Berlin Germany http://tobiasconradi.com/
