#22418 [Asn]: TimeZone.php always returns UTC on Windows

ID: 22418 Updated by: pajoye@php.net Reported By: pear at yogamala dot com Status: Assigned Bug Type: PEAR related Operating System: Windows 2000 PHP Version: 4.3.1 Assigned To: pajoye New Comment: No See peardev archives for the status and "real" solutions. In a few words: win32 platforms do not have any standart for TZ. This patch does not fix the problem. The only good solution is to use the same TZ DB on all platforms (this solution is used by near all date/time related system). That means to use the public TZ DB. pierre Previous Comments: ------------------------------------------------------------------------ [2003-08-16 11:35:21] cellog@php.net has this been fixed in cvs yet so it can be closed? ------------------------------------------------------------------------ [2003-04-28 04:05:39] arnaud@php.net IIRC pierre like Date :) ------------------------------------------------------------------------ [2003-04-06 23:24:22] akimoto at share360 dot com Windows seems only accept 3 letters timezone, unless you use Windows specific names as pear suggested. Another possible fix suggestion is to cut more than 3 letters timezone name before giving it to Windows, like, "EBST3EBDT" -> "EBS3EBD" I am not fully sure, but if this works okay, this is easier to maintain as we could keep the same timezone list, instead of having two lists for Windows and non-Windows platforms. ------------------------------------------------------------------------ [2003-02-25 13:50:27] pear at yogamala dot com Here's the diff to fix it: ?
