@samuelcolvin @davidhewitt This is ready for review but I feel like this is hacky. If you have a better way of doing it I'm all ears 🙏

[davidhewitt]

I think the following might work for these three lines:

Suggested change

	let obj = Py::new(py, tz_info)?.to_object(py);
	Some(Py::new(py, tz_info)?.to_object(py).extract(py)?)

Will rely on type inference for .extract() to give you the &PyTzInfo.

I do think there's some missing API and documentation for PyO3 in this area, just haven't quite decided what the API should look like.

[PrettyWood]

Thank you! I first tried that but had issue with lifetime of variable since Py::new takes ownership of the pointer (hence my usage of from_borrowed_ptr instead. I fixed it in 8f09d8c

[samuelcolvin]

LGTM, @PrettyWood merge if you think this is done.
