If it's based off Debian then it's usually /var/log/ or /var/log/ntpd/
otherwise find / -name ntpd.log should answer your question :)

Well, no, standard advice for refclocks is exactly that. get the time

I think when you have to tinker with drivers anyway, it is better
to adapt a driver from ntpd and leave out gpsd.

gpsd writes the time into the SHM block.
you need a serial port with data and DCD,

I am at the very early stages of building a small stratum-1 NTP server
using a Linux box (Raspberry Pi). A Trimble GPS is connected via USB
(yes, I know I will need an interrupt-driven pin for the PPS), and if I
install gpsd I can see the output from the GPS with the cgps -s command.
How do I
