The same principle seems to work very well i python:

>>> import time
>>> time.time()
974208614.846
>>> time.localtime(time.time())
(2000, 11, 14, 14, 30, 28, 1, 319, 0)
>>> time.localtime(time.mktime((2000, 11, 14, 0,0,0,0,0,0)))
(2000, 11, 14, 0, 0, 0, 1, 319, 0)
>>> time.localtime(time.mktime((2000, -1, 14, 0,0,0,0,0,0)))
(1999, 11, 14, 0, 0, 0, 6, 318, 0)
>>> time.localtime(time.mktime((2000, 0, 14, 0,0,0,0,0,0)))
(1999, 12, 14, 0, 0, 0, 1, 348, 0)

All you have to do is extract the current date from 

  time.localtime(time.time()),

subtract 2 from the month and stuff it back using 

  time.mktime(your_new_date)

and compare.

Good luck.
