Как сделать таймер???

[Sh@man]

onClipEvent (load) {
wait = 5;
starTimer = true;
}
onClipEvent (enterFrame) {
if (starTimer) {
if (startTime == undefined) {
startTime = getTimer()/1000;
}
curTime = getTimer()/1000;
if ((curTime-startTime)>=wait) {
starTimer = false;
delete startTime;
// actions to do after time is up
trace ("bing!");
} else {
_root.timeRemaining = wait-(curTime-startTime);
}
}
}
