Can we really measure time witht taking into acount the error the clock produces?

Question

The clock time changes depending on the energy that is used to measure it ,didnt Frank Harris prove that it in impossible to have a moving clock without affecting the energy required for its measurement?

if a clock loses energy it would tick tack slower and slower till it dies wouldnt it? no matter how many times you take it flying around the earth wouldnd it?

Answer 1

Don't confuse the workings of clocks with the passage of time. Clocks, like any mechanical device, are prone to errors and can fail over time (no pun intended). The passage of time will happen whether we have clock to measure it or not. That makes no difference.

We now do have atomic clocks that utilize the radioactive decays of heavy elements as a measure of time and they are accurate to a billionth of a second, but even atomic clocks are NOT 100% accurate. So as with any measurements we make in the process of scientific study, there will be errors. But I think in most cases, the accuracy of an atomic clock is more than acceptable.

Answer 2

time is relative to speed anyway. A clock was put into a shuttle in orbit around the earth and it was synced with a clock on earth. The clock moving around the earth returned a couple seconds fast.
