ID: 55527 Comment by: junxing dot lin at yahoo dot com Reported by: john at zerocrates dot org Summary: DateTime::__construct throws Exception even when timezone is specified Status: Open Type: Bug Package: Date/time related Operating System: Linux PHP Version: 5.3.8 Block user comment: N Private report: N New Comment: http://www.chihaironline.net Previous Comments: ------------------------------------------------------------------------ [2011-08-28 22:23:49] john at zerocrates dot org Description: ------------ The DateTime constructor throws an Exception warning that it is not safe to rely on the system's timezone settings if you try to construct a DateTime object and haven't somehow specified a timezone, whether by using date_default_timezone_set, the date.timezone setting, or the $timezone argument of DateTime itself. However, there is another way to specify the timezone for a DateTime object, by passing a time string which includes a timezone as the first argument to the constructor. When such a string is given, the $timezone argument is ignored and the timezone given in the string is always used. However, this doesn't prevent the Exception from being thrown, even though a timezone is being specified. To avoid the Exception, you have to have a default timezone set, or you have to pass a DateTimeZone as the second argument, even though neither would actually be used for creating the object. Test script: --------------- <?php ini_set('date.timezone', NULL); try { $date = new DateTime('2011-08-28T00:00:00+0000'); echo $date->format('O'); } catch (Exception $e) { echo 'Exception thrown.'; } echo PHP_EOL; date_default_timezone_set('America/New_York'); try { $date = new DateTime('2011-08-28T00:00:00+0000'); echo $date->format('O'); } catch (Exception $e) { echo 'Exception thrown.'; } Expected result: ---------------- +0000 +0000 Actual result: -------------- Exception thrown. +0000 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55527&edit=1
