This looks great, thanks!

In addition to my other comments, two other things:

As I believe you are a first-time contributor, you should probably add your name to Misc/ACKS.
Maybe add a very simple test to TestModule, like this:

def test_utc_alias(self):
    self.assertIs(UTC, timezone.utc)

Thanks for your contribution!

I had to move the definition of datetime.UTC to the end so that modifications to datetime.timezone.utc doesn't make it a different object.

1. Add UTC definition into C implementation as well (just for
   consistency, there's no particular reason not to simply assign the

2. Move `..versionadded` tag into the right place
