Edit report at http://bugs.php.net/bug.php?id=52454&edit=1 ID: 52454 Updated by: derick@php.net Reported by: ben dot davies at stickyeyes dot com Summary: Relative dates and getTimestamp increments by one day -Status: Open +Status: Assigned Type: Bug Package: Date/time related Operating System: Windows 7 Professional PHP Version: 5.3.3 -Assigned To: +Assigned To: derick Block user comment: N Previous Comments: ------------------------------------------------------------------------ [2010-07-27 11:46:01] ben dot davies at stickyeyes dot com Description: ------------ If you create a DateTime object using a relative date string of "this week +6 days", when calling getTimestamp on the datetime object, the date is mysteriously increments by one day. However, if you seperately modify the datetime using 'this week', then '+6 days', it works correctly. Where is the additional day comeing from, and why is it only applied when calling format('U') DOESNT increment the datetime by 1 day. Wierd! Here is a work around: $endOfWeek = new DateTime(); $endOfWeek->modify('this week'); $endOfWeek->modify('+6 days'); echo $endOfWeek->format('Y-m-d H:m:s')."\n"; echo $endOfWeek->format('U')."\n"; /* Thar she blows! */ echo $endOfWeek->getTimestamp()."\n"; echo $endOfWeek->format('Y-m-d H:m:s')."\n"; Test script: --------------- $endOfWeek = new DateTime(); $endOfWeek->modify('this week +6 days'); echo $endOfWeek->format('Y-m-d H:m:s')."\n"; echo $endOfWeek->format('U')."\n"; /* Thar she blows! */ echo $endOfWeek->getTimestamp()."\n"; echo $endOfWeek->format('Y-m-d H:m:s')."\n"; Expected result: ---------------- DateTime should stay the same after a call to getTimestamp (surely getTimestamp should be safe from side effects) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52454&edit=1
