本文介绍了一个使用ActionScript 3.0 (AS3) 编写的简单程序，该程序能够实现在界面上实时更新当前的日期和时间，并且通过定时器每秒刷新显示的时间。此外，还展示了如何根据系统的当前日期获取对应的星期名称。

private function init():void{
    var timer:Timer = new Timer(1000);
    timer.addEventListener(TimerEvent.TIMER, this.resetTime);
    timer.start();
   }

   private function resetTime(event:TimerEvent):void{
    var today:Date = new Date();
    var dateFormatter:DateFormatter = new DateFormatter();
    var timeFormatter:DateFormatter = new DateFormatter();
    dateFormatter.formatString = "YYYY年MM月DD日";
    timeFormatter.formatString = "HH:NN:SS";
    var time:String = timeFormatter.format(today);
    var date:String = dateFormatter.format(today);
    var week:Number = today.day;
    var weekStr:String = "星期";
    switch(week){
     case 0: weekStr += "日";
      break;
     case 1: weekStr += "一";
      break;
     case 2: weekStr += "二";
      break;
     case 3: weekStr += "三";
      break;
     case 4: weekStr += "四";
      break;
     case 5: weekStr += "五";
      break;
     case 6: weekStr += "六";
      break;
    }
    this.lb_date.text = date + " " + weekStr;
    this.lb_time.text = time;
   }

<mx:Label text="" width="150" height="21" right="111" top="9" id="lb_date"/>
<mx:Label text="" width="80" height="21" right="28" top="9" id="lb_time"/>
