Possible duplicate:
Python date and time for Unix timestamp

Is there a way to convert datetimeto int, representing minutes, since, for example, January 2012, so that this intcan be changed, written to the database, compared and so on? EDIT: The server I am running this uses Python 2.6.6

Subtracting two objects datetime.datetime, you get timedeltaan object that has (added in Python 2.7). Divide this by 60 and type to get minutes from your original date: .total_seconds()int()

import datetime

january1st = datetime.datetime(2012, 01, 01)
timesince = datetime.datetime.now() - january1st
minutessince = int(timesince.total_seconds() / 60)

or in python shell:

>>> import datetime
>>> january1st = datetime.datetime(2012, 01, 01)
>>> timesince = datetime.datetime.now() - january1st
>>> minutessince = int(timesince.total_seconds() / 60)
>>> minutessince
346208

python 2.6 .days .seconds :

minutessince = timesince.days * 1440 + timesince.seconds // 60
