        date - The date from which the time information should be extracted
        Returns:
        A GMT representation of the time given by the date

      • getID

        java.lang.String getID()
        Returns time zone id for this time zone. For time zone objects that have been instantiated from a time zone offset, the POSIX time zone id will be returned.
        Returns:
        time zone id

      • getISOTimeZoneString

        java.lang.String getISOTimeZoneString​(java.util.Date date)
