From: martijn at webfauna dot nl Operating system: Debian 4.6.3 PHP version: 5.5.6 Package: Date/time related Bug Type: Bug Bug description:Inconsistent ISO-8601 hour offset format date_format and date('c') Description: ------------ The formatting of the hour offset in date_format()/DateTime->format() differs from the one in date(). Both are correct according to the ISO-8601 specification, though I would expect a consistent format. Test script: --------------- date_default_timezone_set("Europe/Amsterdam"); $timeStamp = 1276592400; $dateTest = new DateTime(date('c', $timeStamp)); echo $dateTest->format(DateTime::ISO8601) ."\n"; echo date_format($dateTest, DateTime::ISO8601)."\n"; echo date('c', $timeStamp) ."\n"; Expected result: ---------------- EITHER 1276592400 2010-06-15T11:00:00+0200 2010-06-15T11:00:00+0200 2010-06-15T11:00:00+0200 OR 1276592400 2010-06-15T11:00:00+02:00 2010-06-15T11:00:00+02:00 2010-06-15T11:00:00+02:00 Actual result: -------------- 1276592400 2010-06-15T11:00:00+0200 2010-06-15T11:00:00+0200 2010-06-15T11:00:00+02:00 -- Edit bug report at https://bugs.php.net/bug.php?id=66161&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=66161&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=66161&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=66161&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=66161&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=66161&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=66161&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=66161&r=needscript Try newer version: https://bugs.php.net/fix.php?id=66161&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=66161&r=support Expected behavior: https://bugs.php.net/fix.php?id=66161&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=66161&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=66161&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=66161&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=66161&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=66161&r=dst IIS Stability: https://bugs.php.net/fix.php?id=66161&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=66161&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=66161&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=66161&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=66161&r=mysqlcfg
