I think you should let this guy have the last word.Modern technology can accurately measure time to 3.5 parts in quintillion (1018): https://www.newscientist.com/article/2149568-the-most-precise-atomic-clock-ever-made-is-a-cube-of-quantum-gas/
Why you think we can only measure time to 1 part in 1,000 is beyond me...
You are mistaken the time that is produced by a clock with the measurement of a time interval. Example, to measure the time of a person running the 100 meter dash; the measurement uncertainty to measure the time interval to complete the race is dependent on the mechanism that determines when the person starts and stops. The uncertainty of the actual time (3.5 parts in quintillion) is trivial compared to the start-stop uncertainty.
