#41912 [Asn->Bgs]: date() interprets Unix timestamp as GMT and converts it to the default timezone

ID: 41912 Updated by: derick@php.net Reported By: ron@php.net -Status: Assigned +Status: Bogus Bug Type: Date/time related Operating System: Debian GNU/Linux PHP Version: 5.2.3 Assigned To: derick New Comment: I checked this now, and it is not a bug. If you convert to a timestamp there is no more associated timezone possible. The date object keeps this normally - but it's impossible to attach this just to a number. If you add the timezone as output, you will see the difference: <?php date_default_timezone_set('Europe/Amsterdam'); $date = new DateTime('now', new DateTimeZone('GMT')); echo 'DateTime::format(): '.$date->format('Ymd, H:i:s T')."\n"; echo 'date() of unixtime: '.date('Ymd, H:i:s T', $date->format('U'))."\n"; ?> derick@kossu:~$ php bug41912.php DateTime::format(): 20070711, 21:00:26 UTC date() of unixtime: 20070711, 23:00:26 CEST Previous Comments: ------------------------------------------------------------------------ [2007-07-06 08:21:10] ron@php.net Description: ------------ date() interprets a Unix timestamp as GMT and converts it to the default timezone.
