从ISO8601日期时间字符串中提取时区

Question

How to extract time zone from ISO-8601 date string in Java 8.

eg:

   String timestamp1 = "2014-02-15T01:02:03Z" ;
   String timestamp2 = "2017-10-27T16:22:27.605-05:30";

Thanks.

Use ZonedDateTime :

ZonedDateTime.parse("2017-10-27T16:22:27.605-05:30").getZone()

to get an instance of ZoneId .

Alternatively you can use getOffset() to obtain ZoneOffset ,which is more handy if you need to access the timezone offset in a numeric form.
