codefossa Posted October 6, 2013 Share Posted October 6, 2013 If you want something to happen after a certain time, you don't want to rely on client side detection of the end. Ignoring the possibility of someone simply changing it to zero, if nobody triggers it, it would fail as well. You should give what Irate said a shot, using cronjobs. This way the server checks periodically if the time is up and triggers whatever to happen. Nobody can cheat it, and you rely on nobody but yourself. If you set an explicit time, be sure to pay attention to the timezone set on the server. Quote Link to comment Share on other sites More sharing options...
DavidAM Posted October 7, 2013 Share Posted October 7, 2013 I guess I read the question differently. Are you trying to show the user a count-down? Something like: "This offer expires in 1 hour 12 minutes 32 seconds" -- Or are you trying to have some task performed at, say, midnight on Sunday? For the later, a cron job is the way to go for the reasons stated by others. For the former, we probably need a little more information; but JavaScript and AJAX are the direction to start.
