All,

I have set up a raspberry pi as a NTP server.

The Pi is performing flawlessly.

when I run the ntp -pn, I get the following output

      remote           refid      st t when poll reach delay   offset  jitter

Is the pi using the GPS pps signal as the reference clock or the clock at 176.9.72.17 which has
the * infront of it?

Thanks
