Though a bit off topic, the tech behind the swiss railway clock [1] might be of interest to anyone that hasn't read about it. I escpecially enjoy this "low tech" approach to clock synchronization: > The second hand is driven by an electrical motor independent of the master clock. > It requires only about 58.5 seconds to circle the face, then the hand pauses briefly at the top of the clock. > It starts a new rotation as soon as it receives the next minute impulse from the master clock [1]: https://en.wikipedia.org/wiki/Swiss_railway_clock#Technology https://en.wikipedia.org/wiki/Swiss_railway_clock#Technology
