The example should be pretty self explanatory and the docs will give you all the relative info. You'll want to use datetime and datetime.timedelta http://docs.python.org/library/datetime.html and examples of using datetime and datetime.timedelta http://pleac.sourceforge.net/pleac_python/datesandtimes.html Here's the example for figuring out 12 weeks in the past: In [1]: import datetime In [2]: now = datetime.datetime.now() In [3]: diff = datetime.timedelta(weeks=12) In [4]: past = now - diff In [5]: past Out[5]: datetime.datetime(2009, 5, 13, 6, 18, 12, 582151) Mike -- Any circuit design must contain at least one part which is obsolete, two parts which are unobtainable, and three parts which are still under development.
