[time-nuts] GPS module recommendation for Pi timing

[Bob kb8tq]

Hi

One of the ways a GPS module “freaks out” is to slip by one code cycle 
(which is just slightly over 1 ms). If you have a surveyed location, some
firmware will reject the solution and at least you will be in holdover. 

In a case where the *only* thing you can trust is the GPS, filtering isn’t going
to do much good.
