note 71420 added to function.date

Hi guys, im having a hard time on php date. What im planning to do is to create a simple time-in and time-out system. Now i know that we can simply get the current date by using: date("Ymd"); but my problem is what if someone changes the computer tima and date, that would mean that the date that my system will give is the wrong date.. is there any possible way that the correct date will always appear on my system, rather than the date made up by somebody? Please help me.. thanks! ---- Server IP: 66.163.161.117 Probable Submitter: 203.177.1.114 (proxied: 192.168.109.187) ---- Manual Page -- http://www.php.net/manual/en/function.date.php Edit -- https://master.php.net/note/edit/71420 Del: integrated -- https://master.php.net/note/delete/71420/integrated Del: useless -- https://master.php.net/note/delete/71420/useless Del: bad code -- https://master.php.net/note/delete/71420/bad+code Del: spam -- https://master.php.net/note/delete/71420/spam Del: non-english -- https://master.php.net/note/delete/71420/non-english Del: in docs -- https://master.php.net/note/delete/71420/in+docs Del: other reasons-- https://master.php.net/note/delete/71420 Reject -- https://master.php.net/note/reject/71420 Search -- https://master.php.net/manage/user-notes.php
