Research direction

Search the stubs for the declarations of timedelta64 and signedinteger and inspect how their subtype relationships are represented. Verify that the relationship matches the runtime issubclass example and check the relevant type-checking behavior; done means the stubs expose timedelta64 as a signedinteger subtype.

Written by the indexing model from the issue text.

Description

blame: NumPy numpy.generic
>>> import numpy as np
>>> issubclass(np.timedelta64, np.signedinteger)
True

But this isn't reflected in stubs.

LSP-wise, it's rather sketchy, but it has to be done either way.
