note 113967 added to datetime.setisodate

I have found strange behaviour in this code: <?php $year = 2014; $week = 1; $timezone = new DateTimeZone('Europe/Prague'); $date = new DateTime('now', $timezone); $date->setISODate($year, $week); echo $date->format('Y'); // will output 2013 ?> I think this is not ok. Please tell me, if I'm wrong. ---- Server IP: 72.52.91.14 Probable Submitter: 72.52.91.14 ---- Manual Page -- http://php.net/manual/en/datetime.setisodate.php Edit -- https://master.php.net/note/edit/113967 Del: integrated -- https://master.php.net/note/delete/113967/integrated Del: useless -- https://master.php.net/note/delete/113967/useless Del: bad code -- https://master.php.net/note/delete/113967/bad+code Del: spam -- https://master.php.net/note/delete/113967/spam Del: non-english -- https://master.php.net/note/delete/113967/non-english Del: in docs -- https://master.php.net/note/delete/113967/in+docs Del: other reasons-- https://master.php.net/note/delete/113967 Reject -- https://master.php.net/note/reject/113967 Search -- https://master.php.net/manage/user-notes.php
