I don't think anything is wrong with datetime - it's just a stdlib tool that I use on a regular basis. Sorry, wasn't listing just those I think have warts or those replaced by other tools, just libs that I use regularly.

My only gripe with datetime and time are the organization of it. I can never remember whether it's datetime.datetime.now or datetime.now or time.timedelta or datetime.timedelta, and so on.

Yeah, typing datetime.datetime for everything gets pretty old.

I just remember that datetime is the package, datetime.datetime is the class, and datetime.datetime.now() is a @classmethod that returns instances of that class. I do kinda wish it was datetime.now() for the constructor instead.
