From: ulrich dot staerk at spe-siemens dot de Operating system: Windows 2000 PHP version: 4.3.1 PHP Bug Type: Date/time related Bug description: date doesn't return correct number of week
date("W",mktime(0,0,0,1,1,2005)) returns "1" where it should return "53" because January 1st and 2nd still belong to the last week of 2004. In an earlier version of php (4.2.3) on the same machine it simply returned "0" which was wrong too but could be corrected within my script. This bug appears also in January 2006, 2010 (there seems to be an 10-day-long first week :-) ) and so on. -- Edit bug report at http://bugs.php.net/?id=22889&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=22889&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=22889&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=22889&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=22889&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=22889&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=22889&r=support Expected behavior: http://bugs.php.net/fix.php?id=22889&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=22889&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=22889&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=22889&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=22889&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=22889&r=dst IIS Stability: http://bugs.php.net/fix.php?id=22889&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=22889&r=gnused
