Kill a second?

Read here, time is constantly being adjusted, even killed(?)
Unlike the better-known leap year, which adds a day to February in a familiar four-year cycle, the leap second is tacked on once every few years to synchronize atomic clocks — the world’s scientific timekeepers — with Earth’s rotational cycle, which, sadly, does not run quite like clockwork. The next one is scheduled for June 30 (do not bother to adjust your watch).
