I think this is rather neat, myself. My wall clock gets the time signal from WWVB, which is now apparently tied in to the new NIST-F2. If that’s true, then I also have a very accurate clock in my own home.
Well, kind of. Except that NIST-F2 is so accurate that the lag time of the signal going through the servers and pipelines to get to your computer throws the actual timing signal off by orders of magnitude, thereby destroying it's actual accuracy for your particular use.
It's like when they had to cut all of the wires in Fat Man to exactly the same length, so that the detonation signal, traveling at near light-speed, would reach the detonators at the precision level of synchronization that they needed in order to trigger the nuclear warhead.
There's timing, and then there's timing. LOL!
