//First we create a date object. Note that we count the months from “0″!

//next we create a timer that will update the time every second
var timer:Timer = new Timer(1000);
//we add an event listener to the timer and then we start it
timer.addEventListener(TimerEvent.TIMER, updateTime);
timer.start();
//Calculate the time remaining as it is being updated
function updateTime(e:TimerEvent):void{
//we create a variable to hold the current date
var currentDate:Date = new Date();
//we calculate the time to FIFA World Cup 2010
var timeLeft:Number = endDate.getTime() – currentDate.getTime();
//we convert the remaining time into seconds, minutes, hours, and days
var seconds:Number = Math.floor(timeLeft / 1000);

var hours:Number = Math.floor(minutes / 60);

hours %= 24;

//we convert the numbers to strings
var sec:String = seconds.toString();
var min:String = minutes.toString();
var hrs:String = hours.toString();
var d:String = days.toString();

//if we have a single digit we add “0″ in front of it

//we create a variable to hold all elements and then we add it to our text field
