Two corrections... The event handler
argument type would be TimerEvent, not TimerEventType, and you'd start with
timer with timer.start() rather than Timer.start() because start() is an
instance method.
I posted a working example of using Timer
earlier today.

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.

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.

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
