| Does POSIX actually specify the seasonal | adjustment, if applied, has to be 1 hour? No, it doesn't - that's just the default (as it is most common) if an (old style) POSIX TZ string doesn't specify the offset to be applied to summer time. It does specify the 1 hour default though. There's no problem with this part of the TZ specification (other than that TZ strings cannot possibly represent all of the world's timezones - the limit on the offset is 24 hours (ahead or behind UTC), and there's no way to specify an alteration of the zone's offset, other than the seasonal variation (summer time). kre
