clock doesn't start

[ChuckElias]

Wow, that's a tough question. I think that if I were actually in the situation, my instincts would take over and I would blow the whistle and take 2 or 3 seconds off the clock. But you're right in that this would put Team A at a disadvantage. It might be better to count the 5 seconds in your head (or visibly) and then end the game with your whistle. I'm not sure what I would do in that situation. I don't think you could go wrong either way.
