note 95549 added to class.dateinterval

Is this class supposed to exist in 5.2.9 ? I get the following error: PHP Fatal error: Class 'DateInterval' not found in /path/to/datebla.php on line 6 which reads: $p1 = new DateInterval ('P5D'); Thanks, Martijn. ---- Server IP: 83.137.20.135 Probable Submitter: 80.255.245.169 ---- Manual Page -- http://www.php.net/manual/en/class.dateinterval.php Edit -- https://master.php.net/note/edit/95549 Del: integrated -- https://master.php.net/note/delete/95549/integrated Del: useless -- https://master.php.net/note/delete/95549/useless Del: bad code -- https://master.php.net/note/delete/95549/bad+code Del: spam -- https://master.php.net/note/delete/95549/spam Del: non-english -- https://master.php.net/note/delete/95549/non-english Del: in docs -- https://master.php.net/note/delete/95549/in+docs Del: other reasons-- https://master.php.net/note/delete/95549 Reject -- https://master.php.net/note/reject/95549 Search -- https://master.php.net/manage/user-notes.php
