获取每个ISO郡代码的最前沿时区

Question

我正在尝试获取每个国家的时区。如果国家有多个时区，则应使用最靠前/最靠右的时区。例如，对于美国来说，它将是纽约/EST。

有没有办法使用谷歌的时区API来做到这一点？https://developers.google.com/maps/documentation/timezone/

Answer 1

您不需要API。只需使用IANA时区数据库中的zone.tab文件。

许多国家只有一个时区：

TJ  +3835+06848 Asia/Dushanbe
TK  -0922-17114 Pacific/Fakaofo
TL  -0833+12535 Asia/Dili
TM  +3757+05823 Asia/Ashgabat
TN  +3648+01011 Africa/Tunis

正如你所说，像美国这样的国家有很多时区：

我不一定同意你的主张，即应该使用最合适的时区。但如果你想这样做，你可以使用国内经度值最大的一个。
