Some would suggest that introducing a new protocol like

- timedelta(seconds=42).__seconds__

defining an ABC

- class SecondLike(abc.ABC):
-     @abc.abstractmethod
-     def __seconds__(self):
-         raise NotImplementedError

defining an extraction function

- def os.seconds...

and let all stdlib functions which accepts integer/float seconds also 
accept SecondLike objects as the solution to the problem.

I have to admit that I like your idea more.
