Bug #55527 [NEW]: DateTime::__construct throws Exception even when timezone is specified

From: Operating system: Linux PHP version: 5.3.8 Package: Date/time related Bug Type: Bug Bug description:DateTime::__construct throws Exception even when timezone is specified 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 bug report at https://bugs.php.net/bug.php?id=55527&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55527&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55527&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55527&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55527&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55527&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55527&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55527&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55527&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55527&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55527&r=support Expected behavior: https://bugs.php.net/fix.php?id=55527&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55527&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55527&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55527&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55527&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55527&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55527&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55527&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55527&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55527&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55527&r=mysqlcfg
