Bug #64155 [Com]: Weird bug with time handling

Edit report at https://bugs.php.net/bug.php?id=64155&edit=1 ID: 64155 Comment by: cmbecker69 at gmx dot de Reported by: espertalhao04 at hotmail dot com Summary: Weird bug with time handling Status: Open Type: Bug Package: Date/time related Operating System: any linux distro PHP Version: Irrelevant Block user comment: N Private report: N New Comment: I have rewritten your test script to be able to better explain the behavior: <http://3v4l.org/I96tr>. Independently of the default time zone, $time1 has the same value, but $string1 differs for different default time zones, because there is no time zone specified for the conversion (other than the default time zone): $string1 = date('d-m-Y h:i:s', $time1); The following results are logical consequences. So there is clearly no weird bug in time handling, and certainly, specified time zones are taken into account.

You must specify your timezone to perform operations with specified timezone! There was no section to write this, so i put it here: If there is a timezone specified, it should use it to treat this specific date. Possible solution: Verify if the timezone is valid, perform offset calculations and return the date. This way, we would be sure that the date is in the same timezone as specified. Test script: --------------- <?=date('d-m-Y h:i:s',strtotime(date('d-m-Y h:i:s',strtotime('02:07:03 Feb 04, 2013 PST'))." GMT"))."<br>"?> <?date_default_timezone_set('GMT')?> <?=date('d-m-Y h:i:s',strtotime(date('d-m-Y h:i:s',strtotime('02:07:03 Feb 04, 2013 PST'))." GMT"));?> <?=date_default_timezone_get()?> Expected result: ---------------- 04-02-2013 10:07:03 04-02-2013 10:07:03 GMT Actual result: -------------- 04-02-2013 12:07:03 04-02-2013 10:07:03 GMT ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=64155&edit=1
