#49534 [NEW]: Incorrect dates returned with strtotime

From: re dot lewis at comcast dot net Operating system: Linux PHP version: 5.2.10 PHP Bug Type: Date/time related Bug description: Incorrect dates returned with strtotime Description: ------------ On Sept 11, 2009 I was calculating the date for each successive sunday and used the code below, but after Nov 1, 2009, the day changes to Saturday. Is this a bug? It appears to be related to daylight savings time. Reproduce code: --------------- <?php for ($w= 5; $w < 15; $w++) { echo date('Y-m-d, D, z', (strtotime('sunday') + $w*7*24*60*60)) . "<br>"; } ?> Expected result: ---------------- Return the date of each sunday starting 5 weeks from this coming sunday. Actual result: -------------- 2009-10-18, Sun, 290 2009-10-25, Sun, 297 2009-11-01, Sun, 304 2009-11-07, Sat, 310 2009-11-14, Sat, 317 2009-11-21, Sat, 324 2009-11-28, Sat, 331 2009-12-05, Sat, 338 2009-12-12, Sat, 345 2009-12-19, Sat, 352 -- Edit bug report at http://bugs.php.net/?id=49534&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=49534&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=49534&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=49534&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=49534&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=49534&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=49534&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=49534&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=49534&r=needscript Try newer version: http://bugs.php.net/fix.php?id=49534&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=49534&r=support Expected behavior: http://bugs.php.net/fix.php?id=49534&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=49534&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=49534&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=49534&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=49534&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=49534&r=dst IIS Stability: http://bugs.php.net/fix.php?id=49534&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=49534&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=49534&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=49534&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=49534&r=mysqlcfg
