note 87934 added to function.strtotime

found a strange behaviour, maybe this note will save someone else's time. We are the 31st Dec. 2008 and my time is roughly 11:56 GMT+1 (this is not 4 minutes to midnight ;-) So date('M') returns 'Dec', of course. Nos the strange strtotime() behaviour : date('M',strtotime('-1 month')); produces wrong 'Dec' date('M',strtotime('-31 day')); produces correct 'Nov' strange, no ? I checked the differences (in days) between the two strtotime values 'today' and '-1 month' : 29,50 days ; this should be 30.43 (the mean duration of a month, AFAIK) ---- Server IP: 89.31.146.176 Probable Submitter: 82.243.20.181 ---- Manual Page -- http://www.php.net/manual/en/function.strtotime.php Edit -- https://master.php.net/note/edit/87934 Del: integrated -- https://master.php.net/note/delete/87934/integrated Del: useless -- https://master.php.net/note/delete/87934/useless Del: bad code -- https://master.php.net/note/delete/87934/bad+code Del: spam -- https://master.php.net/note/delete/87934/spam Del: non-english -- https://master.php.net/note/delete/87934/non-english Del: in docs -- https://master.php.net/note/delete/87934/in+docs Del: other reasons-- https://master.php.net/note/delete/87934 Reject -- https://master.php.net/note/reject/87934 Search -- https://master.php.net/manage/user-notes.php
