Re: Fortunately, We Know the Title Was Only a Joke
JS suggested "...adjusting the length of the second..."
Hmmm. Simply change the '9,192,631,770 cycles of the caesium 133 etc.' to a different number. Perhaps 9,192,631,867 or thereabouts to give an extra second every three years.
Of course, we'd have to update some PROMs in the time standards, ...not to mention adjust the value of all sorts of derived constants, recalibrate much of the test equipment and electronics on Earth, amend all the text books, etc.
