The old way, which I am familiar with because of my time at Goddard Space Flight Center on the Apollo Timing and tracking system, cesium beam and rubidium beam atomic clocks, now they are going way beyond the microwave signals these atomic beams generate and now are at optical frequencies, at the time of Apollo, the best clock was the hydrogen beam clock, accurate to one second in 6 million years, so this one is three thousand times more accurate than that. The hydrogen clock was about a thousand times more accurate than the cesium beam clocks (made by Hewlett Packard) we used to use.
Time marches on!
It means we can perform experiments about gravity, spacetime, and fundamental constants of science with much more certainty now.

Ah, so you finally admit the universe is billions of years old. About time.
is about scientist trying to make an accurate clock. One day we will know how
and we will all know the truth. Isn't God an awesome Creator? HalleluYah!!!

P.S. They had to admit to a mistake in dating the Shroud of Turin, too.

Everyone makes mistakes, scientists included. The beauty of science however is that it is a process designed to discover and correct mistakes.
so they would not make the mistakes to start with. It can cause animosity
when that happens.

Science deals with this problem by having a process that corrects mistakes.
