Are you asking a Python question, like how to turn a string "1/6/2013 
3:52:69PM" into an internal representation of time, or are you asking a 
data analysis and statistical question?

If the former, then look at datetime.strptime from the datetime module.

If the later, then you may get an answer here, but I'd suggest trying 
somewhere that discusses statistics and analysis.
