It's about time...

I control time now! At least, in the studio. PTP, NTP, GPS, PPS, what's it all about? In this first part to a new time series, I'll show you how I built a Raspberry Pi grandmaster time server for my network. Then I'll see how it compares to a commercial grandmaster clock from MasterClock!
