As a workaround I just ended up setting my timezone in Windows to UTC, not the best solution but it works.

We’ve merged #1987 as an interim solution while dateutil/dateutil#197 remains unresolved. We’ll now perform a best effort fallback to tzwinlocal if we fail to parse the timestamp on Windows. This will maintain backwards compatibility but provide a potential route to recovery for the failure users were previously experiencing.
