I wonder how accurate a reset based on astronomical observations or GPS would be. Just checked out https://www.nist.gov/pml/time-and-frequency-division/time-realization/utcnist-time-scale-0/how-utcnist-works https://www.nist.gov/pml/time-and-frequency-division/time-re... I didn't understand everything, but it looks like they have a fleet of atomic clocks for UTC and are resilient to one of the clocks failing. I guess it is possible that if all of those clocks go down, the world loses track of time. I wouldn't want to be responsible for that cluster :)
