DateTimeZoneCache class

Provides an implementation of DateTimeZoneProvider that caches results from an DateTimeZoneSource.

The process of loading or creating time zones may be an expensive operation. This class implements an unlimited-size non-expiring cache over a time zone source, and adapts an implementation of the IDateTimeZoneSource interface to an IDateTimeZoneProvider.
