I'm not sure I understand the point in renaming the module.
Note that the time module works based on Unix ticks (seconds
since the Unix Epoch), while the datetime module works based
on its own set of types.
As such, the two are different implementations for managing
date/time. Mixing them won't make things easier to understand.
The time module is very close to the C lib API, while the datetime
module focuses more on date/time storage in a more accessible.
I agree on one point, though: the shared C APIs for getting the
current time would be better put into a separate C extension
which both can then load without creating circular references,
