Detailed Description

Base backend class for KTimeZone classes.

KTimeZone and each class inherited from it must have a corresponding backend class to implement its constructors and its virtual methods, and to provide a virtual clone() method. This allows KTimeZone virtual methods to work together with reference counting of private data.

Note:
Classes derived from KTimeZoneBackend should not normally implement their own copy constructor or assignment operator, and must have a non-const d-pointer.
