今天看到这位博客的博主，把Chris Oliver 写的时钟改了一些代码，变成这个样子，呵呵，有兴趣的朋友可以参考下学习下面的源代码：

public class Timer 
{

private attribute elapsed: Number;
7 public attribute minutes: Number;
8 public attribute seconds: Number;
9 public attribute hours: Number;
10 public attribute running: Boolean;
11
}
12
13attribute Timer.elapsed = bind
14if running then
15[1..60] dur 60000 linear
16while running
17continue if true
18else 0;
19
20trigger on Timer.elapsed = value {
21 var now = new Date();
22 minutes = now.getMinutes();
23 seconds = now.getSeconds() +
24 [.35,0.34 .. 0.0] dur 350 +
25 (now.getTime() % 1000)/1000;
26 hours = now.getHours();
27}
