最近在项目中Fix了一个跨时区的bug，为了Fix这个bug真是费了九牛二虎之力呀。就现在看来主要原因还是平时的开发任务没有涉及到这方面的概念，并且测试跨时区功能的Test Case也比较的难写。为了以后能顺利的解决跨时区功能的问题，制作了张跨时区表，总共102个时区：

时区表的用法
假如我想模拟2个时区来写测试case，那么我们可以这样做：
TimeZoneInfo UTC_8 = TimeZoneInfo.FindSystemTimeZoneById("Pacific Standard Time");//-8
TimeZoneInfo UTC_4 = TimeZoneInfo.Local;
DateTime dt_4 = new DateTime(2013, 5, 8, 7, 0, 0); //-4
DateTime dt_8 = TimeZoneInfo.ConvertTime(dt_4, UTC_8);
备注
在这张时区表中，用符号'|'对时区的标准名称和时区对应UTC时间的偏移量值进行了分割，这样做是为了方便检索。在实际使用过程中，我们仅仅需要时区的标准名称（可以参考本文的小例子）。
