#22652 [NEW]: Please add functions to convert between timezones

From: photon at comcast dot net Operating system: Linux PHP version: 4.3.1 PHP Bug Type: Feature/Change Request Bug description: Please add functions to convert between timezones Hi, PHP seems to have some innate knowledge of time zones, but I find it very lacking for this very simple thing. Say I have a server in California, but I live in NJ. An m-time, say, of a file on the server is displayed on my website, but it's in Pacific Time. I want it in Eastern Time. It's not as simple as just adding 3 hours either, as Daylight Savings Time must be taken into effect. Not just one DST crossover either, as the crossovers will be at different times. To these ends, I propose three new date functions for PHP: a generalized converttime(int timestamp, string timezone1, string timezone2) which could be used easily to convert a time between two known DAYLIGHT-AWARE time zones, like so: echo converttime(time(), PT, ET) It would take the timestamp, see if it was daylight-time in PT, calculate the offset, check same for ET, convert. Also convertfromlocal which could do this (known ET timestamp, want to convert to local time): echo convertfromlocal(time(), ET) and convertolocal (say I knew I had a PT timestamp and I wanted it in ET (with the machine running on PST)) echo converttolocal(time(), PT) Thank you :) -- Edit bug report at http://bugs.php.net/?id=22652&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=22652&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=22652&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=22652&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=22652&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=22652&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=22652&r=support Expected behavior: http://bugs.php.net/fix.php?id=22652&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=22652&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=22652&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=22652&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=22652&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=22652&r=dst IIS Stability: http://bugs.php.net/fix.php?id=22652&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=22652&r=gnused
