import datetime
class Time(datetime.datetime):
def __add__(self, other):
return datetime.datetime.__add__(self, datetime.timedelta(0, other, 0))
class Fixnum(int):
def seconds(self):
return self
def minutes(self):
return self*60
def hours(self):
return self*3600
t = Time.now()
print t
print t + Fixnum(30).seconds()
print t + Fixnum(1).minutes()
... of course this is totally un-pythonic, so you just wouldn't do it.
