White Rabbit – sub-nanosecond synchronization for large distributed systems

  Haven't looked into this in depth but sub-nanosecond sync for systems up to 10km apart is interesting since 10km is about 33 light microseconds. There is some trickery going on.

    Yes, it uses phased locked loops and measures phase difference between the master clock and the local clock.
