      • It gives you a much more authoritative answer is all, so your server would operate at a higher stratum – though still leave other servers configured so ntpd can munge all the data. You could also then offer up your server into the public NTP pool (www.pool.ntp.org), doing the community a service.

        Out of interest though, what did you plan to use it for?

  1. Can you get a time-stamp from satellites? It would be a good time-server solution in an enclosed environment.

    • Seems so, here is the raw output:
      # gpspipe -w -n 5 | grep -m 1 TPV
      {"class":"TPV","tag":"MID2","device":"/dev/ttyUSB0","mode":3,"time":"2012-09-17T13:51:32.000Z","ept":0.005,"lat":51.99999999,"lon":-0.500000000,"alt":45.263,"epx":12.393,"epy":12.985,"epv":33.365,"track":179.3168,"speed":0.195,"climb":0.156,"eps":25.97}

      What I don’t know is how accurate or usable that time is.
