Hi,
Using Timer class is simple:
import flash.util.Timer;
var timer:Timer = new Timer(500);
timer.addEventListener(TimerEventType.TIMER, handleTimerEvent);
private function handleTimerEvent(event:TimerEventType)
{
//your code
if(condition)
{
//to stop timer
timer.stop();
}
}
Timer.start();
FlexBuilder 2 comes with help. FYI, I am copying pasting Timer class documentation below:

flash.util
Class Timer
Object
|
+--flash.events.EventDispatcher
|
+--flash.util.Timer
public class Timer
extends EventDispatcher
The Timer class is the interface to Flash Player timers. You can create new Timer objects to run code on a specified time sequence. Use the start() method to start a timer. Add an event listener for the "timer" event to set up code to be run on the timer interval.

Property Summary
delay : Number
The delay, in milliseconds, between timer events.
repeatCount : uint
The total number of times the timer is set to run.
running : Boolean [read-only]
true if the timer is running.
Properties inherited from class Object
prototype
Event Summary
timer A Timer object generates the timer event whenever a timer tick occurs.
Constructor Summary
Timer(delay:Number, repeatCount:uint = 0)
Constructs a new Timer object with the specified delay and repeat state.
Method Summary
restart() : Void
Restarts the timer.
start() : Void
Starts the timer, if it is not already running.
stop() : Void
Stops the timer.
Methods inherited from class EventDispatcher
addEventListener, dispatchEvent, hasEventListener, removeEventListener, toString, willTrigger

Property Detail
delay Property
public delay : Number
The delay, in milliseconds, between timer events.
repeatCount Property
public repeatCount : uint
The total number of times the timer is set to run. If the repeat count is set to 0, the timer continues forever (or until the stop() method is invoked or the program stops). If the repeat count is nonzero, the timer runs the specified number of times.
running Property
public running : Boolean [read-only]
true if the timer is running. false otherwise.
Event Detail
timer Event
Type : TimerEventType
A Timer object generates the timer event whenever a timer tick occurs.
This event has the following characteristics:
Characteristic Description
Target The Timer object that generated this event.
Default Behavior None.
Bubbles No.
Cancelable No. There is no default behavior to cancel.
Objects that generate this event Timer.
Replaces ActionScript 2.0 event(s) None, this event is new.
Example listener function function timerListener(event:TimerEvent) {
trace(event.type); // output: timer
}
Example addEventListener() call someEventDispatcher.addEventListener(TimerEventType.TIMER, timerListener);

Constructor Detail
Timer Constructor
public Timer(delay:Number, repeatCount:uint = 0)
Constructs a new Timer object with the specified delay and repeat state.
The timer does not start automatically; you much call the start() method to start it.
Parameters
delay:Number — The delay between timer events, in milliseconds.
repeatCount:uint (default = 0) — Specifies the number of repetitions. If zero, the timer repeats infinitely. If nonzero, the timer runs the specified number of times and then stops.
Throws
Error — if the delay specified is negative or not a finite number
Method Detail
restart Method
public restart() : Void
Restarts the timer. The timer is stopped, and then started.
start Method
public start() : Void
Starts the timer, if it is not already running.
stop Method
public stop() : Void
Stops the timer.
Example
package {
import flash.util.trace;
import flash.util.Timer;
import flash.events.TimerEvent;
import flash.display.Sprite;
public class TimerExample extends Sprite {
public function TimerExample() {
var myTimer:Timer = new Timer(1000, 2);
myTimer.addEventListener("timer", onTimer);
myTimer.start();
}
public function onTimer(event:TimerEvent):Void {
trace("onTimer: " + event);
}
}
}

Can someone point me to where I can get info on the Timer Class. The
livedocs just ether say see the new Timer Class, or for the Timer Class
it just says TBD :/
