note 99893 added to function.time

i need help i used : echo date("F") ; but the explore says:: Strict Standards: date() [function.date]: It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/Paris' for '2.0/DST' instead in C:\AppServ\www\Untitled-2.php on line 4 help ---- Server IP: 80.64.47.13 Probable Submitter: 84.126.89.129 ---- Manual Page -- http://www.php.net/manual/en/function.time.php Edit -- https://master.php.net/note/edit/99893 Del: integrated -- https://master.php.net/note/delete/99893/integrated Del: useless -- https://master.php.net/note/delete/99893/useless Del: bad code -- https://master.php.net/note/delete/99893/bad+code Del: spam -- https://master.php.net/note/delete/99893/spam Del: non-english -- https://master.php.net/note/delete/99893/non-english Del: in docs -- https://master.php.net/note/delete/99893/in+docs Del: other reasons-- https://master.php.net/note/delete/99893 Reject -- https://master.php.net/note/reject/99893 Search -- https://master.php.net/manage/user-notes.php
