💪 Motivation

...so that I can ensure the start time comes before the stop time.

📖 Additional Details

From original bug ticket: from @jstone-psi:

I was asked by one of our archivists if validate ensures that start_date_time occurs before stop_date_time. I tested this, and found that it does not enforce it.

I expected either an error or a warning if the stop_date_time occurred before the start_date_time.

There are cases where this may be difficult due to precision mismatches in both dates. In that case I would expect a warning regarding the difference in precision, or an attempt to compare them after accounting for the difference.

Acceptance Criteria

Given a label with a start_time > stop_time When I perform label validation Then I expect validate to raise an WARNING
