先在服务器获取系统时间，然后在浏览器上用Javascr ipt使时间走动，实现动态显示。虽然网络传输或者页面显示会有不同的时间缓迟，但也不会缓迟太多，总比如果浏览者计算机系统时间不正确差几个小时要好吧-Being first in the server system time, and then in the browser using Javascr ipt to make time move, dynamic display. Although the network transmission or the page is displayed with a different time slow late, but it will not slow too late, if the viewer than the computer system time is incorrect for a few hours difference Well ~
