Description:
------------
1) The regular 'format' method on datetime objects only accepts date() syntax, which is severely limited in what you can do with it. The strftime syntax is more powerful.

2) As discussed in bug 45167, there's no way to call strftime using datetime object values reliably, because there are ways to create datetime objects with bogus timezone objects (objects which can not be recreated nor can their names be passed to date_default_timezone_set).

Because of 1) and 2), there is a need to get strftime integrated in the datetime class.
