Feature request or enhancement

For feature requests or enhancements, provide this information, please:

Which use case/requirement will be addressed by the proposed feature?

For nullable cols, we send null when we receive a zero date. For not nullable columns, we send the epoch value. It is impossible for consumer to differentiate between true epoch and zero value. Provide a setting to override these columns to nullable so that a special value (null) can be sent when a zero date is encountered that is distinct from the epoch value.

Implementation ideas (optional)

Will put out a PR.
