People complaining that there's no way to set the offset - you are wrong. You can easily set the offset from GMT (see "Other" in available zones). And since all zones are offset from GMT it's just easy math with + or - to get that. So if you i.e. want the offset not from GMT but your timezone, then compute offset of your zone from GMT (say if you in Berlin its +1 now (mind summer time!)) and then offset for your target zone (i.e NYC is -5) then sum abs! of these values and set the sign of bigger (abs) value -> total offset from your european zone to NYC is then abs(-5)+abs(1) = 6 and set "-" as NYC zone absolute value is bigger. So whatever time is in Berlin, in NYC it's 6hrs earlier. But it's better to do two step calculation and calculate always from GMT ---- Server IP: 195.114.0.19 Probable Submitter: 89.229.85.3 ---- Manual Page -- http://www.php.net/manual/en/function.date-default-timezone-set.php Edit -- https://master.php.net/note/edit/101020 Del: integrated -- https://master.php.net/note/delete/101020/integrated Del: useless -- https://master.php.net/note/delete/101020/useless Del: bad code -- https://master.php.net/note/delete/101020/bad+code Del: spam -- https://master.php.net/note/delete/101020/spam Del: non-english -- https://master.php.net/note/delete/101020/non-english Del: in docs -- https://master.php.net/note/delete/101020/in+docs Del: other reasons-- https://master.php.net/note/delete/101020 Reject -- https://master.php.net/note/reject/101020 Search -- https://master.php.net/manage/user-notes.php
