Well, you would really need two of those in perfect sync at start time to do the time-dilation measurement. If you want to implement the second one you will need a method to compensate for the communication delay when you do the measurement in real time. And a really good back support. However I

Actually even crystal oscillators start to lose time in hours... A rubidium can holdover for days and a cesium can holdover for more days... None are perfect. Cesium 133 resonates between different energy states 9,192,631,770 times each second with almost no variation. So a clock that ticks to tha

It's really a matter of what you want for a reference. A Rubidium/Cesium/whatever reference will give you a very stable 10Mhz timing reference, but it *wont* give you the official time-of-day. Every so often, there are corrections to official world time and if you're using a stable timing refer
