利用timer类做的倒计时和顺时

package
{
	import flash.display.Sprite;
	import flash.events.Event;
	
	public class Main extends Sprite
	{
		private var date_chusheng:Date = new Date(1992,6,25,0,0,0,0);
		private var date_siwang:Date = new Date(2072,5,25,0,0,0,0);
		private var datetime_siwang:Number= date_siwang.getTime();
		private var datetime_chusheng:Number = date_chusheng.getTime();
		private var datetime_now:Number;
		private var date_now:Date;
		private var time:Number;
		private var time1:Number;
		public function Main ()
		{
			this.addEventListener(Event.ENTER_FRAME,chusheng);
			this.addEventListener(Event.ENTER_FRAME,siwang);
			
		}
		private function chusheng (e:Event):void
		{
			var date_now = new Date();
		    var datetime_now= date_now.getTime();
			var time = datetime_now-datetime_chusheng;
			var milliseconds = time%1000;
			var seconds:int = time /1000 %60 ;
			var minutes:int = time/1000/60 %60 ;
			var hours:int = time/1000/60/60 %24 ;
			var day:int = time/1000/60/60/24 %30 ;
			var month:int = time/1000/60/60/24 / 30 % 12;
			var year:int = time/1000/60/60/24/30 /12%365;
			shuchu_TXT.text= year+"年"+month+"月"+day+"天"+hours+"小时"+minutes+"分"+seconds+"秒"+milliseconds+"毫秒";
		}
		private function siwang (e:Event):void
		{
			var date_now = new Date();
		    var datetime_now= date_now.getTime();
			var time1 =datetime_siwang- datetime_now;
			var milliseconds1 = time1%1000;
			var seconds1:int = time1 /1000 %60 ;
			var minutes1:int = time1/1000/60 %60 ;
			var hours1:int = time1/1000/60/60 %24 ;
			var day1:int = time1/1000/60/60/24 %30 ;
			var month1:int = time1/1000/60/60/24 / 30 % 12;
			var year1:int = time1/1000/60/60/24/30 /12 %365;
			shuchu1_TXT.text= year1+"年"+month1+"月"+day1+"天"+hours1+"小时"+minutes1+"分"+seconds1+"秒"+milliseconds1+"毫秒";
		}
	}
}

这个东西我做了之后，深深感觉到timer类的强大。AS3之深让我敬畏 ，我还必须快马加鞭，深入其中！努力吧，加油！
