"The Raspberry Pi as a Stratum-1 NTP Server
As an experiment, I purchased one of the low-cost credit-card-size Raspberry Pi computers, and have configured it to run NTP (Network Time Protocol). I have also used this board with a GPS receiver with pulse per second (PPS) output to make a stratum-1 NTP server, but as I know little of Linux, it has taken some time to achieve this aim! There are some helpful Linux commands scattered throughout this page. These notes are almost as much for my own records for the next time I need to visit this project, but I hope they may be helpful to others.
If you want to get started quickly, with the best results for minimum fuss, please see my Raspberry Pi NTP quick-starter page. Please also see that page for issues with the Jessie release of Linux, and with the newer Raspberry Pi model 3."

"There is a cut-out area in the ModMyPi case which will allow connections to the GPIO connector such as ribbon cable which you can easily break out and file down to a neat edge. The sharp-eyed amongst you will notice that three wires are shown - this is because the surplus header had three wires connected, but I only used two - ground (blue) and GPIO 24 (red). The black lead would be GPIO 23 but it is unused and not connected."
