@kgpayne thanks for pushing the target test fixes. I have noticed that I need to add in one of the fixes for #1676 locally before the sqlite tests run. The failures after the type error is corrected are in test_streams and have to do with Unix timestamp which were discussed last year in these links.

Should the SDK accommodate for differing start_date input formats #855
fix(taps): Use recent start_date as starting_replication_value: #759

I am not sure how to move forward with the Unix timestamp failures. The tests are there to keep SDK taps from breaking configurations that have been seen out in production. I am starting to wonder if I should resolve this in my tap-mssql and close this PR since it may break taps or pipelines that are in production. wdyt?

@BuzzCutNorman I agree that, as a breaking change, we should keep this back until v1.0. Added it to the v1.0 Milestone 👍

@kgpayne Thanks🙏 for the direction.
