note 83227 added to function.gmmktime

As an addendum to my previous note (php.net said it was too long and I had to split this part off), I'll leave you with one more fun tidbit. :) (See the note below this one for a full explanation of timezones versus unix timestamps.) 3 AM PST == 11 AM GMT, right? 11 AM _GMT_ > 3 AM _GMT_ (same timezone) right? So, logically, 3 AM PST > 3 AM GMT. (Makes sense right, it is 3 AM in California 8 hours after it is 3 AM in Greenwich.) Now, because timestamps are timezone-independent (or, always GMT/UTC), you get a strange situation. mktime(3) > gmmktime(3). Even though PST is GMT-8, so PST is less than GMT, mktime(3) is _greater_ than gmmktime(3). At first glance you'd probably expect mktime(3) to be less than gmmktime(3), but because of everything I described before, about how timestamps are always GMT/UTC (or, in some senses, no timezone at all), it ends up being "backwards." (Run a few examples yourself if you don't believe me.) Yet another reason not to try to deal with timezones at the timestamp level! ---- Server IP: 69.147.83.197 Probable Submitter: 67.126.53.106 ---- Manual Page -- http://www.php.net/manual/en/function.gmmktime.php Edit -- https://master.php.net/note/edit/83227 Del: integrated -- https://master.php.net/note/delete/83227/integrated Del: useless -- https://master.php.net/note/delete/83227/useless Del: bad code -- https://master.php.net/note/delete/83227/bad+code Del: spam -- https://master.php.net/note/delete/83227/spam Del: non-english -- https://master.php.net/note/delete/83227/non-english Del: in docs -- https://master.php.net/note/delete/83227/in+docs Del: other reasons-- https://master.php.net/note/delete/83227 Reject -- https://master.php.net/note/reject/83227 Search -- https://master.php.net/manage/user-notes.php
