You CAN fetch complete information for a time zone from the ICalTimeZone
class. See also the KTimeZone documentation.

ICalTimeZone is inherited from KTimeZone which provides a generic
interface to time zone data. To access/write xCalendar time zone data, a
new class also inherited from KTimeZone would be needed, tailored to that
particular data source. I don't see any obvious benefit from trying to
create a KCal::TimeZone class separate from this.
