Hi, just a try, as it is not completely clear to me, what you are trying to achieve, as I don't have experiences with the mentioned framework. It seems to me, that you can only reasonably divide timedeltas, not the absolute timestamps, it might be something like the following: >>> april_1st=datetime.datetime(2010, 4, 1, 11, 55, 00) >>> may_1st=datetime.datetime(2010, 5, 1, 11, 54, 03, 123456) >>> delta_dates = may_1st - april_1st >>> delta_in_secs = delta_dates.total_seconds() >>> delta_in_secs 2591943.123456 >>> delta_in_secs / 5.2 498450.60066461534 >>> hth, vbr -- http://mail.python.org/mailman/listinfo/python-list
