So this year there will be a leap second added just before midnight, the first since 2005. As we all go to celebrate New Year’s, I wonder how this will be treated by the TV networks (I don’t recall how it was handled in 2005). Will we start our countdown one second later than usual, so that the 10 second countdown starts at 11:59:51? Or will we all actually celebrate the New Year one second too early? Perhaps the network will add their leap second early to avoid confusion. Will municipalities running fireworks shows start them on time? Do they launch fireworks at that second, or do they try to time it to explode at that second? Will the general public have any clue that a leap second occurred?
