This has got to be the longest preloader ever – the amount of time I have left until I’m out of the Navy:

Which reminds me - here's a handy AS3 class to create a countdown from now until some chosen date (passed as constructor argument):

CountDown.as

package com.onebyonedesign.utils {     

	public class CountDown {     

		private var _targetDate:Date;     

		public function CountDown(d:Date):void { 
			_targetDate = d; 
		}     

		/** 
		 * 
		 * @return	An object with the properties: days, hours, minutes, and seconds 
		 */ 
		public function getTime():Object { 
			var now:Date = new Date(); 
			var secs:Number = (_targetDate.getTime() - now.getTime()) / 1000; 
			return secondsToTime(secs); 
		}     

		private function secondsToTime(secs:Number):Object { 
			var min:Number = Math.floor(secs / 60); 
			var hour:Number = Math.floor(min / 60); 
			var day:Number = Math.floor(hour / 24); 
			min = min % 60; 
			hour = hour % 24; 
			var sec:Number = Math.floor(secs % 60);      

			var days:String = day &lt; 10 ? "0" + day : day.toString(); 
			var seconds:String = sec &lt; 10 ? "0" + sec : sec.toString(); 
			var minutes:String = min &lt; 10 ? "0" + min : min.toString(); 
			var hours:String = hour &lt; 10 ? "0" + hour : hour.toString();      

			return {days:days, hours:hours, minutes:minutes, seconds:seconds}; 
		} 
	} 
}

package com.onebyonedesign.utils {

public class CountDown {

private var _targetDate:Date;

public function CountDown(d:Date):void {

_targetDate = d;

}

/**

* @return An object with the properties: days, hours, minutes, and seconds

public function getTime():Object {

var now:Date = new Date();

var secs:Number = (_targetDate.getTime() - now.getTime()) / 1000;

return secondsToTime(secs);

}

private function secondsToTime(secs:Number):Object {

var min:Number = Math.floor(secs / 60);

var hour:Number = Math.floor(min / 60);

var day:Number = Math.floor(hour / 24);

min = min % 60;

hour = hour % 24;

var sec:Number = Math.floor(secs % 60);

var days:String = day < 10 ? "0" + day : day.toString();

var seconds:String = sec < 10 ? "0" + sec : sec.toString();

var minutes:String = min < 10 ? "0" + min : min.toString();

var hours:String = hour < 10 ? "0" + hour : hour.toString();

return {days:days, hours:hours, minutes:minutes, seconds:seconds};

}

Quick usage:

package {     

	import com.onebyonedesign.utils.CountDown; 
	import flash.display.Sprite; 
	import flash.events.TimerEvent; 
	import flash.utils.Timer;     

	public class CountdownExample extends Sprite {     

		private var birthday:Date = new Date(2008, 11, 28); 
		private var cd:CountDown;     

		public function CountdownExample():void { 
			cd = new CountDown(birthday); 
			beginCount(); 
		}     

		private function beginCount():void { 
			var timer:Timer = new Timer(10000); 
			timer.addEventListener(TimerEvent.TIMER, showCount); 
			timer.start(); 
		}     

		private function showCount(te:TimerEvent):void { 
			var time:Object = cd.getTime(); 
			trace ("Only " + time.days + " days until Devon's birthday!"); 
		} 
	} 
}

package {

import com.onebyonedesign.utils.CountDown;

import flash.display.Sprite;

import flash.events.TimerEvent;

import flash.utils.Timer;

public class CountdownExample extends Sprite {

private var birthday:Date = new Date(2008, 11, 28);

private var cd:CountDown;

public function CountdownExample():void {

cd = new CountDown(birthday);

beginCount();

}

private function beginCount():void {

var timer:Timer = new Timer(10000);

timer.addEventListener(TimerEvent.TIMER, showCount);

timer.start();

}

private function showCount(te:TimerEvent):void {

var time:Object = cd.getTime();

trace ("Only " + time.days + " days until Devon's birthday!");

}

At least there is more green than red. This loader bar and it’s progress reminds me of installing things on Vista. Or rather, trying to install things on Vista.
