what is the OFFICIAL rule for clock stoppage in the last two minutes of the first half? please explain and also tell the refs. we`ve had different rules all year long. one game the clock stops the next it runs.

And the games Monday night the ref didnt even have a stopwatch! It was cold and his hands never came out of his pockets. And by the way the "hour" long game ended way early, maybe a watch would have helped.

Clock stops on a incomplete pass or penalties etc, However the clock will start again on the refs whistle???? Basically get back on the ball.
