实验: 用访问站点首页面的方法来进行系统较时

来源：互联网发布：263云通信企业版mac 编辑：程序博客网时间：2024/05/16 09:14

公司的网络只能上已经开通的站点, Windows较时失败.

公司开通的网站有google, csdn, codeproject.这3个站点同时关掉的可能性几乎没有.

那做个较时工具, 避免迟到早退.

先访问这两个站点之一, 然后把首页Html文件的时间作为得到的较时时间

(是啥时间忘了，反正这个时间是服务器那边的时间), 用这个时间来矫正Windows本地时间.

程序完成

应用了用户自定义异常, 来简化错误处理, 进一步完善了错误处理的应用, 可以用到正式工程中.
