Question

In this Python package there is this code:

>>> dt = DateTime('Mar 9, 1997 13:45:00 US/Eastern')
>>> dt.timeTime()
857933100.0

I would use this package but there is a warning: “Unless you need to communicate with Zope 2 APIs, you’re probably better off using Python’s bult-in datetime module.”

TimeProperty in GAE gives me something like this 02:37:31.797000 How do I convert it to a number as in the example so that I can add an integer to it and sort by the new value. I want to achieve some kind of weighed sort. Thanks.

EDIT

@Robert Kluin:

Thanks; this works:

>>> today = datetime.datetime.today().toordinal()
>>> today
734086
>>>

But I have a DateTime object that I am using in the query to sort; so this works:

    QUERY2 = Rep.all()
    QUERY2.filter("mAUTHOR =", user)
    QUERY2.order("-mDATE")
    RESULTS2 = QUERY2.fetch(10)

But when I try this, it does not work:

    QUERY2 = Rep.all()
    QUERY2.filter("mAUTHOR =", user)
    QUERY2.order("-(datetime.datetime.mDATE.toordinal())")
    RESULTS2 = QUERY2.fetch(10) 

I get the error:

PropertyError: Invalid property name '(datetime.datetime.mDATE.toordinal())'

This is the value of mDATE as printed by the template:

mDATE = 2010-11-10 05:38:55.340000

Check out the time module.

import time
value = time.time()
