@sagaxu。。你好专业啊
美国中部时间：Central Standard Time (USA) UT-6:00
澳大利亚中部时间：Central Standard Time (Australia) UT+9:30
中国标准时间：China Standard Time UT+8:00
古巴标准时间：Cuba Standard Time UT-4:00
貌似不单独是美国时间吧，可以自己调整的吧。

@Betacoefficient JDK 代码里写死了，CST 就是芝加哥时间，你自己如何调整？

private static String[][] oldMappings = new String[][]{{"ACT", "Australia/Darwin"}, {"AET", "Australia/Sydney"}, {"AGT", "America/Argentina/Buenos_Aires"}, {"ART", "Africa/Cairo"}, {"AST", "America/Anchorage"}, {"BET", "America/Sao_Paulo"}, {"BST", "Asia/Dhaka"}, {"CAT", "Africa/Harare"}, {"CNT", "America/St_Johns"}, {"CST", "America/Chicago"}, {"CTT", "Asia/Shanghai"}, {"EAT", "Africa/Addis_Ababa"}, {"ECT", "Europe/Paris"}, {"IET", "America/Indiana/Indianapolis"}, {"IST", "Asia/Kolkata"}, {"JST", "Asia/Tokyo"}, {"MIT", "Pacific/Apia"}, {"NET", "Asia/Yerevan"}, {"NST", "Pacific/Auckland"}, {"PLT", "Asia/Karachi"}, {"PNT", "America/Phoenix"}, {"PRT", "America/Puerto_Rico"}, {"PST", "America/Los_Angeles"}, {"SST", "Pacific/Guadalcanal"}, {"VST", "Asia/Ho_Chi_Minh"}};
