[help] Timer Question, Is there another way?

[Gloo pot]

I am creating a timer using a dynamic text boxs, is there a way to tell my timer to plus 1 every second with out having to refer the frame rate?

i was using the following untill i realised it was affected by frame rate...

on the frame one i have

_root.mils = 0;
_root.secs = 0;

and in a empty MC i have the following controls

onClipEvent (enterFrame) {
             _root.sec.text = _root.secs;
             _root.mil.text = _root.mils
}
onClipEvent (enterFrame) {
	_root.mils+= 1;
}
onClipEvent (enterFrame) {
	if (_root.mils== 10) {
		_root.mils= 0;
		_root.secs += 1;
	}
}

Can i do the following without having to worry about the frame rate

[EDIT] : I also have 2 Dynamic text boxes, sec and mil...
