Date Comparison and Manipulation Functions?

[W. eWatson]

I just tried the following code, and got an unexpected result.

from pyfdate import *
t = Time()

ts = Time(2008, 8, 29,15,20,7)
tnew = ts.plus(months=6)
print "new date: ", tnew

Result:
new date:  2009-02-28 15:20:07

I believe that should be April 1, 2009. If I use months = 1 and day =31, I 
get Sept. 30, 2008 and not Oct. 1, 2008. Is there a way to get around this?
