Support micro and milli resolution on timestamps

Supporting higher precision on our timestamps seems worthwhile, and
useful to logging implementations for getting more accurate numbers from
redfish LogService interfaces.

This commit updates the code to add millisecond and microsecond
precision to timestamps.

Tested: Unit tests pass, pretty good coverage here.
