A colleague suggested it might be some sort of pickling issue, passing the generated object back to the main thread, but it was just speculation and I had no idea how to test that.

Yes, it must be something of that sort. Here's perhaps an even more minimal example: ```

import cftime; import distributed header, frames = distributed.protocol.serialize(cftime.DatetimeNoLeap(2000, 1, 1)) distributed.protocol.deserialize(header, frames) cftime.datetime(2000, 1, 1, 0, 0, 0, 0, calendar='noleap', has_year_zero=True) Further, removing `distributed` from the mix, we can show this just using `pickle`: import pickle serialized = pickle.dumps(cftime.DatetimeNoLeap(2000, 1, 1)) deserialized = pickle.loads(serialized) deserialized cftime.datetime(2000, 1, 1, 0, 0, 0, 0, calendar='noleap', has_year_zero=True) ``` I'll make an issue in cftime.
