note 91799 added to datetime.settimezone

In my setup setTimezone() does modify the date, as well as the TZ. Code: $dt_obj = new DateTime('2009-06-25 12:00:00'); echo $dt_obj->format(DATE_RFC822) . "\n"; $dt_obj->setTimezone(new DateTimeZone('GMT')); echo $dt_obj->format(DATE_RFC822); Output: Thu, 25 Jun 09 12:00:00 -0400 Thu, 25 Jun 09 16:00:00 +0000 ---- Server IP: 208.69.120.35 Probable Submitter: 173.59.245.145 ---- Manual Page -- http://www.php.net/manual/en/datetime.settimezone.php Edit -- https://master.php.net/note/edit/91799 Del: integrated -- https://master.php.net/note/delete/91799/integrated Del: useless -- https://master.php.net/note/delete/91799/useless Del: bad code -- https://master.php.net/note/delete/91799/bad+code Del: spam -- https://master.php.net/note/delete/91799/spam Del: non-english -- https://master.php.net/note/delete/91799/non-english Del: in docs -- https://master.php.net/note/delete/91799/in+docs Del: other reasons-- https://master.php.net/note/delete/91799 Reject -- https://master.php.net/note/reject/91799 Search -- https://master.php.net/manage/user-notes.php
