It would help in knowing that it's not a bug. A list of valid abbreviations would also be useful. Thanks Test script: --------------- <?php $date = new DateTime('Feb 13, 2009 11:31:30 PM', new DateTimeZone('Indian/Maldives')); echo $date->format('T').PHP_EOL; $date = date_create('Feb 13, 2009 11:31:30 PM', timezone_open('Indian/Maldives')); echo date_format($date, 'T').PHP_EOL; Expected result: ---------------- MVT MVT Actual result: -------------- +05 +05 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76748&edit=1
