Summary
-------

DateTimeStringConverter exposes internal implementation details by mistake. They are made deprecated for removal.

Problem
-------

DateTimeStringConverter has protected members that allow access to its internal state. These should not be part of the public API.

Solution
--------

Deprecate for removal the protected access members so that they can be removed from public API.

Specification
-------------
