Subject: [PATCH] Fix flaky expires_at tests

The API parameter is not a timestamp but an offset.
If a sufficient amount of time passes between the tests
expires_at calculation and the internal calculation during processing
of the request the strict equality assertion fails. (Either a direct
assertion or indirect via job lookup).

To avoid this lower comparison granularity.
