Looks OK. I can confirm this fixes the python3 build. There are some datetime associated test errors in python3, some of which I recall from before, but I think those are unrelated to the current changes so I'll put it in.

FAILED (KNOWNFAIL=5, errors=2, failures=2)

Done.

Thanks, the string datetime test failures are because the "string" array doesn't return strings in Python 3. I think they should return strings instead of bytes, the current convention is just weird. Will have to bring this up on the list later at some point.
