is it a threatening sentence? like a father to a daughter, or a boss to an employee??
what does it actually mean?

You've got it exactly.

Be here on time or else there will be consequences to pay!

(Although parent to child is the most common use I can think of. I can't imagine my boss saying that to me, unless he was joking around.)

Hmm...It does sound a bit threatening..By the way, I think the end of the sentence should not have the exclamation mark. Instead, it should end with ''...''.
