How to resume after clock starts during throw-in that is untouched.

[Afrosheen]

I’ve had multiple scenarios now where the clock started prematurely. Now the concern that I have is where to resume play? At where the ball was located when the clock malfunction was identified or at the original spot of the throw-in?

I can’t find any material on this. I’m wondering if say the play is an alley-oop with three seconds left and the throw-in is from the sideline. Clock starts without anyone touching it and the only thing that happens is that the ball bounces off the backboard untouched and then bounces out of bounds on the end line. Where would the play be resumed from?

Or another play would be the ball is rolled in from the end line in the backcourt. The ball rolls into the front court and then you find out the clock started prematurely. Where would the throw-in be located?
