Bug #53340 [NEW]: getTimestamp returns wrong values for DateTimes from DatePeriods

From: Operating system: Linux PHP version: 5.3.3 Package: Date/time related Bug Type: Bug Bug description:getTimestamp returns wrong values for DateTimes from DatePeriods Description: ------------ When using a DatePeriod, calling getTimestamp on the objects returns wrong results, starting with the second Datetime. This is probably connected with http://bugs.php.net/bug.php?id=52454 and might have been fixed by it's solution. I'm on gentoo 64bit testing using php-5.3.3. Also confirmed on debian 32bit using php5.3.2-1. Test script: --------------- <?php $start = new Datetime('2010-11-10 08:00:00 UTC'); $delta = new DateInterval('P1D'); $snd = new Datetime('2010-11-11 08:00:00 UTC'); $period = new DatePeriod($start, $delta, 3); echo 'We should get: ' . $snd->getTimestamp() . "\n"; $manual = clone $start; $manual->add($delta); echo 'Manually adding: ' . $manual->getTimestamp() . "\n"; foreach ($period as $p) { // work around getTimestamp modifying date http://bugs.php.net/bug.php?id=52454 $timestamp = $p->getTimestamp(); echo 'From DatePeriod: ' . $timestamp . ', '; $tmp = new Datetime('@' . $timestamp); echo 'which is really: ' . $tmp->format('Y-m-d H:i:s') . ', ' . $tmp->getTimezone()->getName() . "\n"; } Expected result: ---------------- We should get: 1289462400 Manually adding: 1289462400 From DatePeriod: 1289376000, which is really: 2010-11-10 08:00:00, +00:00 From DatePeriod: 1289462400, which is really: 2010-11-11 08:00:00, +00:00 From DatePeriod: 1289548800, which is really: 2010-11-12 08:00:00, +00:00 From DatePeriod: 1289635200, which is really: 2010-11-13 08:00:00, +00:00 Actual result: -------------- We should get: 1289462400 Manually adding: 1289462400 From DatePeriod: 1289376000, which is really: 2010-11-10 08:00:00, +00:00 From DatePeriod: 1289548800, which is really: 2010-11-12 08:00:00, +00:00 From DatePeriod: 1289635200, which is really: 2010-11-13 08:00:00, +00:00 From DatePeriod: 1289721600, which is really: 2010-11-14 08:00:00, +00:00 -- Edit bug report at http://bugs.php.net/bug.php?id=53340&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=53340&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=53340&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=53340&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=53340&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=53340&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=53340&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=53340&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=53340&r=needscript Try newer version: http://bugs.php.net/fix.php?id=53340&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=53340&r=support Expected behavior: http://bugs.php.net/fix.php?id=53340&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=53340&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=53340&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=53340&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=53340&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=53340&r=dst IIS Stability: http://bugs.php.net/fix.php?id=53340&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=53340&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=53340&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=53340&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=53340&r=mysqlcfg
