From: Operating system: CentOS 5 PHP version: 5.3.8 Package: Date/time related Bug Type: Bug Bug description:DateTime doesn't use default timezone
Description: ------------ DateTime doesn't appear to use the default timezone (set either in php.ini or with date_default_timezone_set()). It's currently BST in the UK and without calling setTimeZone() on a DateTime object, format() will produce a date/time that is one hour behind. If setTimeZone() is called on a DateTime object then the date/time produced by format() is correct. date() by itself uses the default timezone that has been set. For consistency, DateTime should do also. Test script: --------------- <pre> <?php date_default_timezone_set('Europe/London'); $now = time(); // Initialising with a timestamp, second DateTimeZone parameter would be ignored. $dt1 = new DateTime('@' . $now); echo 'DateTime->format()', "\t", $dt1->format('Y-m-d H:i:s T Z e'); echo "\n"; $dt2 = new DateTime('@' . $now); $dt2->setTimeZone(new DateTimeZone('Europe/London')); echo 'DateTime->format()', "\t", $dt2->format('Y-m-d H:i:s T Z e'); echo "\n"; echo 'date()', "\t\t\t", date('Y-m-d H:i:s T Z e', $now); ?> <pre> Expected result: ---------------- $dt1->format() should use Europe/London as the timezone and show the correct time for that timezone. Actual result: -------------- $dt1->format() shows +00:00 as the timezone and is an hour behind. -- Edit bug report at https://bugs.php.net/bug.php?id=55642&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55642&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55642&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55642&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55642&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55642&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55642&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55642&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55642&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55642&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55642&r=support Expected behavior: https://bugs.php.net/fix.php?id=55642&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55642&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55642&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55642&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55642&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55642&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55642&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55642&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55642&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55642&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55642&r=mysqlcfg
