比较两个时间的大小和时间差

---------------------------------比较时间的大小-------------------------------------------------

---------------------------------得到当前时间-------------------------------------------------

---------------------------------得到当前时间-------------------------------------------------
-----------得到一个区域的时间，然后计算出时间差，并显示到指定的位置---------------------------
