UNIX timestamps are in GMT by definition -- it's the functions that work with them that do the timezone adjustments. (Compare mktime(12,0,0,9,1,2004) and gmmktime(12,0,0,9,1,2004), for example.) > Am I missing something here, I do I really need to know the > GMT offset > of every event? My opinion on that would be a "Yes", if you're storing events that can take place in multiple timezones. Your only other option, which would effectively give you your "local timestamp", is to treat every date/time entered as if it were GMT, and always use the gm*() functions (or force-add a "GMT" marker to strings passed to strtotime()). That way, no timezone adjustments are ever done, and any one user sees times as originally entered -- but you can't do cross-timezone comparisons because they're not timezone adjusted. Oh, and you probably still need to do manual tracking of DST. Cheers!
