note 119325 added to function.date

When using 'U' to return a UNIX time stamp, you may not get what you expect. In the following example, we try to get the current Unix time stamp for a user in a different timezone. <?php // Doesn't work $timezone = new \DateTimeZone($userTimeZone); $date = new \DateTime('@' . time(), $timezone); $date->setTimezone($timezone); $now = $date->format('U'); ?> $now will return the same (the server's current) Unix time stamp regardless which timezone your user is in. To get the actual Unix time stamp based on a time zone, replace format('U') as in the following example; <?php // This works $timezone = new \DateTimeZone($userTimeZone); $date = new \DateTime('@' . time(), $timezone); $date->setTimezone($timezone); $now = $date->getTimestamp() + $date->getOffset(); ?> ---- Server IP: 72.52.91.14 Probable Submitter: 31.50.141.245 ---- Manual Page -- http://php.net/manual/en/function.date.php Edit -- https://master.php.net/note/edit/119325 Del: integrated -- https://master.php.net/note/delete/119325/integrated Del: useless -- https://master.php.net/note/delete/119325/useless Del: bad code -- https://master.php.net/note/delete/119325/bad+code Del: spam -- https://master.php.net/note/delete/119325/spam Del: non-english -- https://master.php.net/note/delete/119325/non-english Del: in docs -- https://master.php.net/note/delete/119325/in+docs Del: other reasons-- https://master.php.net/note/delete/119325 Reject -- https://master.php.net/note/reject/119325 Search -- https://master.php.net/manage/user-notes.php
