note 87922 added to function.mktime

I'm trying to add 25 hours to a date to get the next date. echo date('o-m-d H:i:s', mktime( 25,0,0, 12,27,2008 )); correctly outputs: 2008-12-28 01:00:00 echo date('o-m-d H:i:s', mktime( 25,0,0, 12,28,2008 )); incorrectly outputs: 2009-12-29 01:00:00 Is this a bug in mktime or am I doing something wrong? ---- Server IP: 64.71.164.2 Probable Submitter: 67.79.71.114 ---- Manual Page -- http://www.php.net/manual/en/function.mktime.php Edit -- https://master.php.net/note/edit/87922 Del: integrated -- https://master.php.net/note/delete/87922/integrated Del: useless -- https://master.php.net/note/delete/87922/useless Del: bad code -- https://master.php.net/note/delete/87922/bad+code Del: spam -- https://master.php.net/note/delete/87922/spam Del: non-english -- https://master.php.net/note/delete/87922/non-english Del: in docs -- https://master.php.net/note/delete/87922/in+docs Del: other reasons-- https://master.php.net/note/delete/87922 Reject -- https://master.php.net/note/reject/87922 Search -- https://master.php.net/manage/user-notes.php
