I have some questions about NTP timing in the Raspberry Shakes.
In the documentation I found this:
If you need excellent relative timing for active seismic studies, for example, then you can improve the relative timing precision by setting up a Raspberry Shake as the daemon NTP server and slaving all other Raspberry Shakes to it.
Does it have to be a Raspberry Shake or can it be a Raspberry with a GPS, since, from my understanding, all the other Raspberry Shakes will see it as an NTP server?
What is the benefit of such a solution? Will I have better accuracy than using the same NTP server for all my Raspberry Shakes?
