Interesting. So a second now is longer than a second was 200 years ago.

That must be why the metric system second is defined as:

"the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom"

What a clear and easy to understand measurement! Why, it would only take one 4 096 315 885 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom to see how superior the metric system is!
