note 117862 added to class.datetime

It seems like, due to changes in the DateTimeZone class in PHP 5.5, when creating a date and specifying the timezone as a a string like 'EDT', then getting the timezone from the date object and trying to use that to set the timezone on a date object you will have problems but never know it. Take the following code: <?php $date = new DateTime('2015-08-21 15:00:00 EDT') ; $tz_string = $date->getTimezone()->getName() ; $tz = new DateTimeZone($tz_string) ; $date->setTimezone($tz) ; ?> You would think this code should not change $date at all, but it does. It seems like you can create a timezone object like 'EDT' but can't use those to set timezones properly. The process, however does act like it's working without errors. ---- Server IP: 72.52.91.14 Probable Submitter: 98.103.111.174 ---- Manual Page -- http://php.net/manual/en/class.datetime.php Edit -- https://master.php.net/note/edit/117862 Del: integrated -- https://master.php.net/note/delete/117862/integrated Del: useless -- https://master.php.net/note/delete/117862/useless Del: bad code -- https://master.php.net/note/delete/117862/bad+code Del: spam -- https://master.php.net/note/delete/117862/spam Del: non-english -- https://master.php.net/note/delete/117862/non-english Del: in docs -- https://master.php.net/note/delete/117862/in+docs Del: other reasons-- https://master.php.net/note/delete/117862 Reject -- https://master.php.net/note/reject/117862 Search -- https://master.php.net/manage/user-notes.php
