Forgive me if I’m wrong, but aren’t you the author of the date time module? If that’s
the case what you expect it to do isn’t particularly relevant as you’re intimately aware
of it’s implementation.

It’s hard to do any sort of search for this, however in an informal poll where I’ve shown
people this code not a single person thought it made sense, and most of them responded
with “wtf?”. I’ve also seen first hand through Django (which is why the person who started
this thread) get caught by this bug and have to spend hours trying to figure out why it’s
behaving that way.
