Could you also post output from ntpq -p

I don't have a pc with recent FreeBSD but the desktop
I updated to NetBSD-6 only 2 hours ago gives:

remote                refid        st t poll reach delay offset jitter
+ntp1.lordynet.org    81.187.61.74  2 u  512   377 0.450 -4.961  3.024

Does the Sure have a PPS output you can use?

<Local pc> is using a Sure with PPS
# ntpq -c rv -p me6000
associd=0 status=0119 leap_none, sync_pps, 1 event, leap_armed,
version="ntpd 4.2.6p5....",
processor="i386", system="NetBSD/5.1_STABLE",
.....
offset=-0.001 sys_jitter=0.004
