Did seconds exist before the earth existed?

Cecil:

Seconds probably came into existence the first time, the first man/woman
noticed that sand falling though a narrow opening could be useful in
measuring motion and distance (specifically the rotation of the earth in
the heavens--is my guess. But, I do admit earlier devices--suns
movement, moons movement, heavens movement, movement of the shadow from
a stick, etc.)

But, you already knew that... But, if you are speaking of "Universal
Time Frame" seconds--I don't believe anyone claims to have detected
them--yet, I wonder about the UTF with no formed opinion.

Now, what argument do you propose for me enjoy thinking about?
