#38330 [NEW]: Checkdate reports false on good dates

From: thomasvk at gmail dot com Operating system: Windows XP SP2 PHP version: 5.1.4 PHP Bug Type: Unknown/Other Function Bug description: Checkdate reports false on good dates Description: ------------ checkdate() returns false on two correct dates, which are 29 February 4905 and 30 February 8228, according to the following source (warning: Dutch!): http://home.wanadoo.nl/~haj.quast/pages/schrikkeljaar.htm I shall translate/quote the paragraph concerning these dates: Correction in the future According to calculations the next correction is due in the year 4905. In this year there will be an extera leapday so it will be 29 February two years in row. A next correction shall be due in the year 8228. That year is already a leapyear in itself so there will be a 30 February. I hope there's a dev who understands Dutch to confirm this. Reproduce code: --------------- $x = checkdate(2, 29, 4905) $y = checkdate(2, 30, 8228) Expected result: ---------------- $x = checkdate(2, 29, 4905) // $x should be true $y = checkdate(2, 30, 8228) // $y should be true Actual result: -------------- $x and $y should both become true. -- Edit bug report at http://bugs.php.net/?id=38330&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=38330&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=38330&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=38330&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=38330&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=38330&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=38330&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=38330&r=needscript Try newer version: http://bugs.php.net/fix.php?id=38330&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=38330&r=support Expected behavior: http://bugs.php.net/fix.php?id=38330&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=38330&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=38330&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=38330&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=38330&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=38330&r=dst IIS Stability: http://bugs.php.net/fix.php?id=38330&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=38330&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=38330&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=38330&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=38330&r=mysqlcfg
