Why datetime module is so complicated?

[Zeynel]

It's about a week now I've been trying to convert a datetime object to
seconds since epoch; the object is set to current time by class Rep()
in Google App Engine:

class Rep(db.Model):
    ...
    mCOUNT = db.IntegerProperty()
    mDATE0 = db.DateTimeProperty(auto_now_add=True)
    mWEIGHT = db.FloatProperty()

I want to divide mDATE0 by the integer mCOUNT. I asked the same
question here previously and also at stackoverflow. So far, I still
cannot make it work. I would greatly appreciate if someone who is an
expert in datetime operation in Python could help me understand this
issue. Thank you.
