are you sure property on the model is not going to do it for you?
something like
def get_interval( self ):
return datetime.timedelta( days = self.interval_days, minutes =
self.interval_minutes )
def set_interval( self, timed ):
self.interval_days = timed.days
.....
interval = property( get_interval, set_interval )
its not perfect, but you wouldn't have to worry about it in the code
and/or hack Django...

that said, I think this would be a nice contribution, having an
IntervalField... ;)
you just have to make sure it works with all the supported DB's.
just let me know (here, personal email, [EMAIL PROTECTED], icq, ...) if you
would like some help with that...
