Tenses in Hypothetical Sentences?

Let's set some context:

Person A knocks on person B's door.

Person B: "Oh no! He's here to rob us!" (bear with me)

Person A: "If I was here to rob you, I wouldn't have knocked."

I know this is a hypothetical statement, but is this a hypothetical statement for the past, or present?

Could be present because the person is explaining why the person is at the house.

Could be past because the person said I wouldn't have knocked, referring to the past.
