For what it's worth, modules actually *are* allowed to contain a class
of the same name: for example, datetime.datetime.
Anyway, what this error message is actually trying to tell you is that
you are attempting to call a module as a function somewhere -- and in
this particular case, I think it's referring to the time module. Are
you sure that line 98 in Hook_m.py should not instead be:
dt = self.Date(time.time())
The time module contains a function, time(), which returns the current
Unix time (another example of a module containing an object of the same
name, incidentally); but you'll need to call this function as
"time.time()" unless you have prefaced your code with
from time import time
or
from time import *
Otherwise, the token "time" refers to the time module, which is not
callable, and not the desired function therein.
