Answer 1

new Date().time returns the time in milliseconds.

var nStart:Number = new Date().time;

// Some time passes

var nMillisElapsed:Number = new Date().time - nStart;

var strTime:String = Math.floor(nMillisElapsed / (1000 * 60 * 60)) + "::" + 
   (Math.floor(nMillisElapsed / (1000 * 60)) % 60) + "::" + 
   (Math.floor(nMillisElapsed / (1000)) % 60);
