[GromNaN]

Fix PHPORM-143
Fix #2719

In #2705 (a5cf5cb), the conversion from MongoDB\BSON\UTCDateTime to Carbon\Date was modified in a way that no longer change use the local timezone. UTCDateTime::asDateTime always return a DateTime instance with UTC timezone, while le previous Date::createFromTimestampMs($timestampMs) was using the local timezone.

This test permanently alters the state of the environment. Would it be preferable to capture the current timezone first and then restore it at the end of the test?

If you're concerned about a failure interrupting things, you can use tearDown(), but I don't think that's necessary.

The timezone is reset before each test by this: https://github.com/orchestral/testbench-core/blob/bf3de053bc6566210c0c336635d03e97e270f205/src/Concerns/CreatesApplication.php#L389-L391

But I can explicitly reset the timezone to prevent any regression.

Ah, I didn't realize the tests in this project used OrchestraTestCase instead of PHPUnit directly. I think a comment explaining that would be sufficient.

LGTM pending the timezone things in the tests.

LGTM with a comment explaining the timezone being changed isn't a problem.
