#30357 [NEW]: Date function returns incorrect results

From: vidya at webwisesage dot com Operating system: Unix PHP version: 4.3.8 PHP Bug Type: Date/time related Bug description: Date function returns incorrect results Description: ------------ I wrote a little program below that shows the problem. This simply adds 1 day to the date and prints the date. At Oct 31st, 2004, it prints 2004-10-31 TWICE. In other words, the date function is returning an incorrect result. Reproduce code: --------------- <?php define("ONEDAY",86400); // seconds in a day $startdate = "20041001"; $timestamp = strtotime($startdate); for($i=0; $i<95; $i++): $timestamp = $timestamp + ONEDAY; $workingdate = date("Y-m-d",$timestamp); echo("NEXT DAY IS $workingdate <br>"); endfor; ?> Expected result: ---------------- All dates from 10-02-2004 until 01-02-2005 printed one after the other in sequence. Actual result: -------------- NEXT DAY IS 2004-10-26 NEXT DAY IS 2004-10-27 NEXT DAY IS 2004-10-28 NEXT DAY IS 2004-10-29 NEXT DAY IS 2004-10-30 NEXT DAY IS 2004-10-31 NEXT DAY IS 2004-10-31 NEXT DAY IS 2004-11-01 NEXT DAY IS 2004-11-02 NEXT DAY IS 2004-11-03 NEXT DAY IS 2004-11-04 NEXT DAY IS 2004-11-05 -- Edit bug report at http://bugs.php.net/?id=30357&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=30357&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=30357&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=30357&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=30357&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=30357&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=30357&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=30357&r=needscript Try newer version: http://bugs.php.net/fix.php?id=30357&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=30357&r=support Expected behavior: http://bugs.php.net/fix.php?id=30357&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=30357&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=30357&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=30357&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=30357&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=30357&r=dst IIS Stability: http://bugs.php.net/fix.php?id=30357&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=30357&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=30357&r=float MySQL Configuration Error: http://bugs.php.net/fix.php?id=30357&r=mysqlcfg
