Hello, The last 25 hours I measured the jitter of my RPi-with-userspace PPS processing. In the following graph you'll see those measurements. Each row is an hour: http://vps001.vanheusden.com/~folkert/jitter-hm.png There's some kind of wave in it which I cannot explain: everything not related to timekeeping (apart from sshd) is disabled on that device. No cron, no at, not even the processes that monitor the state of the network port. Allan deviation: http://vps001.vanheusden.com/~folkert/allandev.png
