Two timers in one? HELP?

programming flash
1

This is what my code looks like right now.

var Timer1:Timer = new Timer(500);
var Timer2:Timer = new Timer(2500);

Timer1.addEventListener(TimerEvent.TIMER, OnStart);

Timer1.start();
Timer2.start();
 
function OnStart(e:Event){

Alot of code here.

But I kinda need to do like this:
Timer1 || Timer2.addEventListener(TimerEvent.TIMER, OnStart);
But that doesnt work ofcourse. So how can I solve that? I kinda need everything to be in this EventListener, otherwise it will be alot of code.
