Description: ------------ Feeding a decimal value to DateTime's modify() function can cause very long execution times because the decimal point is ignored. Reproduced on the php5.3-200808200230 snapshot. Reproduce code: --------------- $date = new DateTime(); $date->modify("+1.61538461538 day"); Expected result: ---------------- A warning or exception, or perhaps 1 day + 0.61538461538*24 hours added. Actual result: -------------- after 32 seconds of execution, 161538461538 days are added to the date -- Edit bug report at http://bugs.php.net/?id=45866&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=45866&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=45866&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=45866&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=45866&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=45866&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=45866&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=45866&r=needscript Try newer version: http://bugs.php.net/fix.php?id=45866&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=45866&r=support Expected behavior: http://bugs.php.net/fix.php?id=45866&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=45866&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=45866&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=45866&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=45866&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=45866&r=dst IIS Stability: http://bugs.php.net/fix.php?id=45866&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=45866&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=45866&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=45866&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=45866&r=mysqlcfg
