Bug #55327 [NEW]: mktime produces different results with different formats

From: Operating system: Linux PHP version: 5.3.6 Package: Date/time related Bug Type: Bug Bug description:mktime produces different results with different formats Description: ------------ For August 1, 2011, mktime produces different results based on the input format of the month parameter. Sounds goofy, yes. But calculations based on whether the Aug 1 date is in the future or past may fail if a leading zero is entered for the month. Test script: --------------- echo 'mktime (0,0,0,8,01,2011) = '.mktime (0,0,0,8,01,2011). '<br />'; echo 'mktime (0,0,0,08,01,2011) = '.mktime (0,0,0,08,01,2011). '<br />'; echo 'mktime (0,0,0,7,01,2011) = '.mktime (0,0,0,7,01,2011). '<br />'; echo 'mktime (0,0,0,07,01,2011) = '.mktime (0,0,0,07,01,2011). '<br />'; Expected result: ---------------- mktime (0,0,0,8,01,2011) = 1312171200 mktime (0,0,0,08,01,2011) = 1312171200 mktime (0,0,0,7,01,2011) = 1309492800 mktime (0,0,0,07,01,2011) = 1309492800 Actual result: -------------- mktime (0,0,0,8,01,2011) = 1312171200 mktime (0,0,0,08,01,2011) = 1291179600 <- value is too small mktime (0,0,0,7,01,2011) = 1309492800 mktime (0,0,0,07,01,2011) = 1309492800 -- Edit bug report at https://bugs.php.net/bug.php?id=55327&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55327&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55327&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55327&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55327&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55327&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55327&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55327&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55327&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55327&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55327&r=support Expected behavior: https://bugs.php.net/fix.php?id=55327&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55327&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55327&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55327&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55327&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55327&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55327&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55327&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55327&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55327&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55327&r=mysqlcfg
