Atomic clocks would get you far below the 1ms threshold. I'll rephrase to within 25ms, since that can be pretty acceptable and doable across the internet by just popping up NTP. Without a synchronizing service, time can't be trusted to be accurate. Time should always (try) be absolute to a global time, and not individual clocks a devop manually put some numbers in for.
