This is absolutely correct.

Of course.   But the expectation is that you'd also run all of the
other tests for all of the other interfaces that you have (I am sure
your team of paid professionals has created such tests) with the test
time zone.

That way you get to discover whether any of your interfaces have problems,
before things are being deployed in real timezones, and have time to
make corrections.
