Restart timer on ZERO

Hi Guys, i am using this code for my timer

_root.onEnterFrame = function() {
time = Math.round(getTimer()/1000);
if (time == 120) {
_root.remaining.gotoAndPlay(“objectsRemaining”);
}

It’s being used in a game. So when they re-start the game, i want to reset the timer to start again on zero. How do i do that?

Thanks for your help.
