/**

The CTzUserData class allows the client to create, read, update or delete

user-defined time zones. 

A user-defined time zone is comprised of time zone rules (encapsulated in a

CTzRules object) and time zone names (encapsulated in a CTzUserNames object).

A time zone identifier (encapsulated in a CTzId object) is used to uniquely

identify a user-defined time zone.

The CTzUserData class also allows the time zone identifiers for all existing

user-defined time zones to be determined.
