I tried:

  NUMBER_OF_MIN=40 #my          


        

Answer 1

Check out the datetime library, which provides much more flexibility for math using dates.

For example:

import datetime
print datetime.datetime.now()
print datetime.datetime.now() - datetime.timedelta(minutes=2)
print datetime.datetime.now() - datetime.timedelta(seconds=10)
print datetime.datetime.now() - datetime.timedelta(milliseconds=400)

Prints:

el@dev ~ $ python test.py
