Does time need to come off the clock on TO?

B1 gains possesion
Timer starts clock
Coach calls time out
Official blows whistle
It's not hard to believe the horn would go off in 6/10ths either.

If in the OP, the Official knows and the Timer knows a time out is coming....but yet the timer does not get the clock started and then stopped within 6/10ths....and the horn goes off.....game over?
