Timing mechanism for ice hockey

  During Ice Hockey precious seconds waste away at every whistle from the time the whistle is blown to the time the timekeeper presses the button to stop the clock. In hockey the clock always stops when the whistle is blown.
  So the logical thing is a device that sends a signal directly to stop the clock whenever the whistle is blown.
  This will mean the full 60 minutes is played, and no more time wasted while coaches ask for time to put back on during important games.
