#46993 [NEW]: strtotime inconsistently parses M-j-Y and Y-M-j format dates

From: anomie at users dot sourceforge dot net Operating system: Linux PHP version: 5.3CVS-2009-01-02 (snap) PHP Bug Type: Date/time related Bug description: strtotime inconsistently parses M-j-Y and Y-M-j format dates Description: ------------ M-j-Y format dates are parsed correctly if the day is 10-31, but as M-j-Hi if the day is 1-9. Or, you could say that M-j-Hi format dates are parsed correctly if the day is 1-9, but incorrectly if the day is 10-31. Y-M-j format dates are parsed correctly if the day is 10-31, but as Y-M in the timezone UTC-j if the day is 1-9. Or, you could say that this odd method of specifying the time zone fails for UTC-10, UTC-11, and so on. Both M-d-Y and Y-M-d formats are parsed correctly for all days. I would find it more consistent if the M-j-Y and Y-M-j formats were recognized for all days, as the other option would conflict with M-d-Y and Y-M-d recognition and both "M-j-Hi" and "Y-M"-with-timezone seem to be unlikely input formats. This bug is also present in PHP 5.2.6. Reproduce code: --------------- date_default_timezone_set("UTC"); echo date("Y-m-d H:i:s\n", strtotime("Dec-9-2006")); echo date("Y-m-d H:i:s\n", strtotime("9-Dec-2006")); echo date("Y-m-d H:i:s\n", strtotime("2006-Dec-9")); echo date("Y-m-d H:i:s\n", strtotime("Dec-10-2006")); echo date("Y-m-d H:i:s\n", strtotime("10-Dec-2006")); echo date("Y-m-d H:i:s\n", strtotime("2006-Dec-10")); Expected result: ---------------- 2006-12-09 00:00:00 2006-12-09 00:00:00 2006-12-09 00:00:00 2006-12-10 00:00:00 2006-12-10 00:00:00 2006-12-10 00:00:00 Actual result: -------------- 2009-12-09 20:06:00 2006-12-09 00:00:00 2006-12-01 09:00:00 2006-12-10 00:00:00 2006-12-10 00:00:00 2006-12-10 00:00:00 -- Edit bug report at http://bugs.php.net/?id=46993&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=46993&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=46993&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=46993&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=46993&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=46993&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=46993&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=46993&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=46993&r=needscript Try newer version: http://bugs.php.net/fix.php?id=46993&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=46993&r=support Expected behavior: http://bugs.php.net/fix.php?id=46993&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=46993&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=46993&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=46993&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=46993&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=46993&r=dst IIS Stability: http://bugs.php.net/fix.php?id=46993&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=46993&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=46993&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=46993&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=46993&r=mysqlcfg
