[issue2267] datetime.datetime operator methods are not subclass-friendly

[Paul Komkoff]

New submission from Paul Komkoff <[EMAIL PROTECTED]>:

The datetime.datetime class overrides some arithmetic operations for it
to be able to add or subtract timedeltas. However, the result of A + B
operation, where A is instance of a subclass of datetime and B is
timedelta instance will be always the instance of base datetime.

This is extremely annoying and requires to override arithmetic operators
and writing a lots of rubbish to replace the datetime base object with
type(self)

I just checked the astimezone method - it also does this.

As with timedelta... well, it's not critical for me now but it worth
thinking about :)
