#39782 [NEW]: setTime() on a DateTime constructed with a Weekday yields incorrect results

From: php at michaelho dot com Operating system: Max OS X 10.4.7 PHP version: 5.2.0 PHP Bug Type: Date/time related Bug description: setTime() on a DateTime constructed with a Weekday yields incorrect results Description: ------------ When calling setTime() on a DateTime that has been constructed with a Weekday (e.g. new DateTime('Wednesday'))... Calling setTime() causes the date to "jump" to the Next Sunday. This happens on each and every call to setTime(). Reproduce code: --------------- <?php $dttTest = new DateTime('Next Wednesday'); print $dttTest->format('D M j Y - H:i:s') . '<br/>'; /* Correctly outputs: "Wed Dec 13 2006 - 00:00:00" */ $dttTest->setTime(12, 0, 0); print $dttTest->format('D M j Y - H:i:s') . '<br/>'; /* EXPECTING: "Wed Dec 13 2006 - 12:00:00" */ /* ACTUAL: "Sun Dec 17 2006 - 12:00:00" */ $dttTest->setTime(12, 0, 0); print $dttTest->format('D M j Y - H:i:s') . '<br/>'; /* EXPECTING: "Wed Dec 13 2006 - 12:00:00" */ /* ACTUAL: "Sun Dec 24 2006 - 12:00:00" */ ?> Expected result: ---------------- Wed Dec 13 2006 - 00:00:00 Wed Dec 13 2006 - 12:00:00 Wed Dec 13 2006 - 12:00:00 Actual result: -------------- Wed Dec 13 2006 - 00:00:00 Sun Dec 17 2006 - 12:00:00 Sun Dec 24 2006 - 12:00:00 -- Edit bug report at http://bugs.php.net/?id=39782&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=39782&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=39782&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=39782&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=39782&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=39782&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=39782&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=39782&r=needscript Try newer version: http://bugs.php.net/fix.php?id=39782&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=39782&r=support Expected behavior: http://bugs.php.net/fix.php?id=39782&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=39782&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=39782&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=39782&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=39782&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=39782&r=dst IIS Stability: http://bugs.php.net/fix.php?id=39782&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=39782&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=39782&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=39782&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=39782&r=mysqlcfg
