flv duration

[pumpkin2006]

hello, im using this:

import fl.video.*; 

flvPlayback.addEventListener(MetadataEvent.METADATA_RECEIVED, timeListener); 

var durationTime:String 
function timeListener(eventObject:MetadataEvent):void { 
   var totalSeconds = String(eventObject.info.duration); 
   durationTime = (totalSeconds > 3600 ? Math.floor(totalSeconds / 3600) + ":" : "") + (totalSeconds % 3600 < 600 ? "0" : "") + Math.floor(totalSeconds % 3600/60) + ":" + (totalSeconds % 60 < 10 ? "0":"") + totalSeconds % 60; 
   //totalTime.text = durationTime; 
} 
stage.addEventListener(Event.ENTER_FRAME, updateTime); 

function updateTime (event:Event):void { 
   var elapsedSeconds = String(flvPlayback.playheadTime); 
   var runTime:String = (elapsedSeconds > 3600 ? Math.floor(elapsedSeconds / 36000) + ":" : "") + (elapsedSeconds % 36000 < 600 ? "0" : "") + Math.floor(elapsedSeconds % 36000/60) + ":" + (elapsedSeconds % 60 < 10 ? "0":"") + elapsedSeconds % 60 ; 
   elapsedTime.text = (runTime + ":" + durationTime);//<----here is where time shows 
} 

to display my flvs' duration, works a treat except it displays the time to about a million decimal places and i only want minutes and seconds, is there a way i can round this up to the nearest second?

thanks!
