I want to create new Timed CHallenge and maybe send it (i hear, that Users can send their own task to the service).
But I've got a (big) problem.
In all task I can see "you have x second...". How can I write script, with I can check time with it? For example, someone will run script at 17:50:25. He has only 2 sec. to type good answer in the form. If he send the solution at 17:50:28, script will "say": quick?
Thanks for reply in advance Wink

I would guess they just use microtime() right after the opening tag, then again once you submit, and if the difference between second-first is <= the time limit, you pass the mission. You may have to cast it to a float, some of the examples I see do.
