out of curiosity, are there any amateur/semi-pro experiments that can measure the length of the solar or sidereal day to sub-millisecond resolution? To reproduce data like this: https://upload.wikimedia.org/wikipedia/commons/5/5b/Deviation_of_day_length_from_SI_day.svg
Something in the sky that goes "ping" every day - detected with a pointing accuracy of < 1ms/24h or <0.01 arc-seconds (!?). Or perhaps two satellite-dishes pointed at the sun and noise-correlation/interferometry??
