When does the moving clock run slow? What is the duration of the test? Or, you got two clocks synchronized together it's March 3rd, 9pm Tuesday, year 2020 and they are off! When does the race end to look at the results? When does the moving clock run slow? one minute after, 2 minutes later, a week, a month? a year?? When does the moving clock run slow?
