Examples of VTimeZone

com.ibm.icu.util.VTimeZone
VTimeZone is a class implementing RFC2445 VTIMEZONE. You can create a VTimeZone instance from a time zone ID supported by TimeZone. With the VTimeZone instance created from the ID, you can write out the rule in RFC2445 VTIMEZONE format. Also, you can create a VTimeZone instance from RFC2445 VTIMEZONE data stream, which allows you to calculate time zone offset by the rules defined by the data.

Note: The consumer of this class reading or writing VTIMEZONE data is responsible to decode or encode Non-ASCII text. Methods reading/writing VTIMEZONE data in this class do nothing with MIME encoding. @stable ICU 3.8
