Did you read what I posted?

Read what the man has said and realise he has answered you.

I already know everything he's saying, so it definitely doesn't answer my question.

He totally failed tell me how adding a year works in Date::Manip. He keeps telling me there are corner cases (which I already do know), and that doesn't answer the question at all.

who's forgotten more on the subject than you will ever allow yourself to know

Stop lying. You have no way of knowing that's true.

Stop trolling. The answer to ignorance isn't to not ask questions.
