When I would need it (and did not find a better method),
I would use (in an external method):

  1. convert to a Python time tuple
  2. add 6 to the month component (creating a new tuple)
  3. convert back to a DateTime object.

It might be necessary to normalize the time tuple
before 3. with an "time.localtime(time.mktime(tup))".
