Bug #53833 [Opn->Wfx]: DateTime::createFromFormat's DateTimeZone parameter ignored

Edit report at http://bugs.php.net/bug.php?id=53833&edit=1 ID: 53833 Updated by: derick@php.net Reported by: alex dot joyce at staff dot comcen dot com dot au Summary: DateTime::createFromFormat's DateTimeZone parameter ignored -Status: Open +Status: Wont fix Type: Bug Package: Date/time related Operating System: Debian 5.0.3 PHP Version: 5.3.5 Block user comment: N Private report: N New Comment: This behaviour is written down in the docs: http://uk3.php.net/manual/en/datetime.construct.php the @ also means a timezone of UTC here. If I would be writing this code again, then I would most likely not have done it like this; but changing it breaks BC (including some of my own code), so I don't think I would like to change it now. Previous Comments: ------------------------------------------------------------------------ [2011-01-25 03:43:59] alex dot joyce at staff dot comcen dot com dot au Description: ------------ I'm loading a DateTime object by a UNIX timestamp. I assumed it would use the local timezone configured (e.g. date() behavior) but it defaults to UTC. When passing a DateTimeZone object into the third parameter of DateTime::createFromFormat, it does nothing. Setting the timezone using DateTime::setTimezone after the DateTime object has loaded gives the correct result. See examples. Test script: --------------- <?php $time = 1293800400; $tz = new DateTimeZone('Australia/Sydney'); // assumes local timezone var_dump(date('r', $time)); // sets to "+00:00", should assume local timezone var_dump(DateTime::createFromFormat('U', $time)); // sets to "+00:00", ignores given DateTimeZone object var_dump(DateTime::createFromFormat('U', $time, $tz)); // adjusts to given timezone correctly var_dump(DateTime::createFromFormat('U', $time)->setTimezone($tz)); Expected result: ---------------- string(31) "Sat, 01 Jan 2011 00:00:00 +1100" object(DateTime)#2 (3) { ["date"]=> string(19) "2011-01-01 00:00:00" ["timezone_type"]=> int(3) ["timezone"]=> string(16) "Australia/Sydney" } object(DateTime)#2 (3) { ["date"]=> string(19) "2011-01-01 00:00:00" ["timezone_type"]=> int(3) ["timezone"]=> string(16) "Australia/Sydney" } object(DateTime)#2 (3) { ["date"]=> string(19) "2011-01-01 00:00:00" ["timezone_type"]=> int(3) ["timezone"]=> string(16) "Australia/Sydney" } Actual result: -------------- string(31) "Sat, 01 Jan 2011 00:00:00 +1100" object(DateTime)#2 (3) { ["date"]=> string(19) "2010-12-31 13:00:00" ["timezone_type"]=> int(1) ["timezone"]=> string(6) "+00:00" } object(DateTime)#2 (3) { ["date"]=> string(19) "2010-12-31 13:00:00" ["timezone_type"]=> int(1) ["timezone"]=> string(6) "+00:00" } object(DateTime)#2 (3) { ["date"]=> string(19) "2011-01-01 00:00:00" ["timezone_type"]=> int(3) ["timezone"]=> string(16) "Australia/Sydney" } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=53833&edit=1
