- * <code>VTimeZone</code> is a class implementing RFC2445 VTIMEZONE. You can create a

- * in RFC2445 VTIMEZONE format. Also, you can create a <code>VTimeZone</code> instance
- * from RFC2445 VTIMEZONE data stream, which allows you to calculate time
- * zone offset by the rules defined by the data. Or, you can create a
- * <code>VTimeZone</code> from any other ICU <code>BasicTimeZone</code>.
- * <br><br>
- * 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.
