Timer event, simple question

programming flash
1

I have a few movieclip, i want them to show up in succession, some at the same time.

Trying to work out the timer event

var myTimer:Timer = new Timer(2000); // 1 second
myTimer.addEventListener(TimerEvent.TIMER, showA);

myTimer.start();

function showA(event:TimerEvent):void {
trace("A");
trace("B");
}

how do i print A
then B after one second, without replicating the code above for each clip.
