It's not "equally braindead", it follows a simple and logical rule:
Only the day portion is negative. That might not be perfectly suited
to all situations, but it does mean that adding and subtracting whole
days will never change the representation of the time. That's a
reasonable promise. What you propose is completely arbitrary, and yes
it WOULD be braindead to have str() return that (although of course
this should be accepted as input).

Doesn't need a PEP. Just subclass it or monkey-patch it and use it as
you will. :)
