AS3 timer works in game - actionscript-3

Question

I have a countdown timer I made in AS3 the start, stop, and reset works fine in the game.
Problem: This Flash app is now inserted into an external virtual-life game as some animated billboard/sign. Each "person" in the game sees the sign but must click the (Flash) button, inside the sign, to start the timer code. Only the person pressing button can see it working. Everyone is given 05:00 minutes to present their offer.
I need everyone in a room to see timer countdown since its for a auction.
Any help I would appreciate it.
This is what I tried to use so far:
package {
import flash.display.MovieClip;
import flash.utils.Timer;
import flash.events.TimerEvent;
import flash.events.MouseEvent;
import flash.ui.Mouse;
public class timerClass extends MovieClip
{
var myTimer:Timer = new Timer(1000, 300);
var i:Number = 300;
public function timerClass()
{
//# constructor code
timerTxt.text = String("05:00");
myTimer.addEventListener(TimerEvent.TIMER, updateTime);
myTimer.addEventListener(TimerEvent.TIMER_COMPLETE, TimerComplete);
startbutton.addEventListener(MouseEvent.CLICK, StartNow);
pausebutton.addEventListener(MouseEvent.CLICK, PauseNow);
restartbutton.addEventListener(MouseEvent.CLICK, restartNow);
}
private function updateTime(e:TimerEvent)
{
i--;
var totalSeconds:* = i;
var minutes:* = Math.floor(totalSeconds/60);
var seconds:* = totalSeconds % 60;
if(String(minutes).length < 2)
{
minutes = "0" + minutes;
if(String(seconds).length < 2)
seconds = "0" + seconds;
}
timerTxt.text = minutes + ":" + seconds;
}
private function TimerComplete(e:TimerEvent)
{
messageTxt.text = "PRESENTATION IS NOW OVER"
timerTxt.text = String("00:00");
}
private function StartNow(e:MouseEvent)
{ myTimer.start(); }
private function PauseNow(e:MouseEvent)
{ myTimer.stop(); }
private function restartNow(e: MouseEvent): void
{
myTimer.stop();
myTimer = new Timer(1000, 300);
myTimer.addEventListener(TimerEvent.TIMER, updateTime);
myTimer.addEventListener(TimerEvent.TIMER_COMPLETE, TimerComplete);
i = 300;
messageTxt.text = "";
timerTxt.text = String("05:00");
}
} //#end Class
} //#end Package
I need everyone in a room to see timer countdown since its for a auction
This is what timer should look like, I just need eveyone to see counter at same time once i press start.
