CET is still +1, while CEST is +2. If you take a look at the official IANA tzdata: http://www.iana.org/time-zones/repository/releases/tzdata2014e.tar.gz For europe, it's something like "std: CET" and "dst: CEST". The current doc is not correct either; we should write something like "either +1 or +2 depending on DST" (there seems to be a 2dst as well which gets +3 offset); Usually the best way of handling timezones is to use the proper location format (e.g. TZ='Europe/Rome') and then letting the system pick the proper offset; we might say something like ' "Europe/Rome" which is +1 in winter ' in the doc, but I'd say that's nitpicking. -- contact me at public@[mysurname].eu -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
