Back in the olden days, mechanical clocks, even if everything was working correctly, could be stopped with 0:00 on the scoreboard with no horn for a split second. In addition, occasionally the timekeeper would accidentally turn off a switch for an automatic horn, and the horn would never sound at the end of the period.
Do these problems still exist with modern digital clocks?
