How to Create a Flash timer with setInterval and clearInterval.

setInterval(function,timeout);

Calls function every timeout (in miliseconds). Returns intervalId.

clearInterval(intervalID);

Cancels an interval created by a call to setInterval().

Example:

function outoftime()
{
	Edit1 = "Out of time";
	clearInterval(interval1); // stop repeating this function
}

// set 2000 miliseconds timer (2000 ms = 2 seconds)
interval1 = setInterval(outoftime,2000);
