Python 3.6 datetime.fromtimestamp throws error when setting 0

Question

In Python 3.5.2, this works:

datetime.datetime.fromtimestamp(0) returns -> datetime.datetime(1970, 1, 1, 1, 0) 

In Python 3.6, however, I get

 datetime.datetime.fromtimestamp(0) -> OSError: [Errno 22] Invalid argument 

I cannot find any changes to the function in the docs. I am curious why this violates my scripts now and where I can find the reasons.

Can anyone shed some light on this?
