Project 02 Stop Watch

I found that after I hit the "Pause" button, then after a while I hit "Resume" button, the time just slip straight to the current time. It seems that the "Pause" button only did the facial work（View）. The time actually didn't stop.
我发现点了"Pause"之后一会儿再点"Resume"，时间就一下跳了。可见"Pause"只停了表面的View。没有停下内部的时间。
