The same function written two ways.

ClockFormats.as

//Traditional Way
public function getClockFormat1(milliseconds:Number):String 
{
        var seconds:Number = milliseconds / 1000;
	var m:int = 0;
	if (seconds > 0) {

			seconds -= 60;

		return String((m < 10 ? "0" : "") + m + ":" + (seconds < 10 ? "0" : "") + seconds);
	}else{
		return "00:00";
	}
}

//My way
public function getClockFormat2(milliseconds:Number):String 
{
	var seconds:Number = milliseconds / 1000;
			
	var hh:Number = Math.floor(seconds / 3600);
	var mm:Number = Math.floor((seconds % 3600) / 60);
	var ss:Number = Math.floor(seconds % 3600 % 60);
			
	var cf:String = String((hh < 10 ? "0" + hh : hh) + ":" + (mm < 10 ? "0" + mm : mm) + ":" + (ss < 10 ? "0" + ss : ss));
