Yes. Also if d.tzinfo is not None but d.tzinfo.utcoffset(d) returns 0 or None.

Because if utcoffset() returns None it's misleading to pretend to be able to return a UTC tuple.
I'd rather get rid of utctimetuple(), supply a datetime.utc tzinfo subclass out of the box, and change the spelling of
d.utctimetuple() to d.timetuple(tzinfo=utc) Similarly for datetime.now() vs datetime.utcnow(). The proliferation of ABCutcXYZ methods is confusing, especially since they return naive objects.
Tell you what. I sincerely doubt that we'll be able to agree on useful semantics for the common base API. /F's proposal doesn't map well on datetime, and that pretty much kills the idea.
