#36861 [NEW]: strtotime off by .04 seconds

From: rikkext1 at drdanger dot com Operating system: xp / linux PHP version: 5.1.2 PHP Bug Type: Date/time related Bug description: strtotime off by .04 seconds Description: ------------ I tripped across this bug calculating the number of days between two dates. It seems like something goes screwy in April and 0.041666667 seconds get dropped. The code below checks the difference in days between May 31 and the first 10 days of April. Reproduce code: --------------- for ($iyear=2000;$iyear<= 2006;$iyear++) { $s_st=$iyear."-03-31"; $st=strtotime($s_st); for ($i=1;$i<=10;$i++) { $addsecs=$st + ($i * 60 * 60 * 24); $end = st + $addsecs; $s_end=Date("Y-m-d",$end); $end = strtotime($s_end); $idiff = ($end - $st) / (60 * 60 * 24); echo("Start: $s_st End: $s_end Diff: $idiff<br>"); } echo("<hr>"); } Expected result: ---------------- I would expect to see the number of days between the dates in question Actual result: -------------- Here's the results for just for 2006 Start: 2006-03-31 End: 2006-04-01 Diff: 1 Start: 2006-03-31 End: 2006-04-02 Diff: 2 Start: 2006-03-31 End: 2006-04-03 Diff: 2.9583333333333 Start: 2006-03-31 End: 2006-04-04 Diff: 3.9583333333333 Start: 2006-03-31 End: 2006-04-05 Diff: 4.9583333333333 Start: 2006-03-31 End: 2006-04-06 Diff: 5.9583333333333 Start: 2006-03-31 End: 2006-04-07 Diff: 6.9583333333333 Start: 2006-03-31 End: 2006-04-08 Diff: 7.9583333333333 Start: 2006-03-31 End: 2006-04-09 Diff: 8.9583333333333 Start: 2006-03-31 End: 2006-04-10 Diff: 9.9583333333333 -- Edit bug report at http://bugs.php.net/?id=36861&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=36861&r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=36861&r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=36861&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=36861&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=36861&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=36861&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=36861&r=needscript Try newer version: http://bugs.php.net/fix.php?id=36861&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=36861&r=support Expected behavior: http://bugs.php.net/fix.php?id=36861&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=36861&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=36861&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=36861&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=36861&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=36861&r=dst IIS Stability: http://bugs.php.net/fix.php?id=36861&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=36861&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=36861&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=36861&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=36861&r=mysqlcfg
