Quite scary, for the following reason:
$ ntpq -c peers tick.usno.navy.mil
remote refid st t when poll reach delay offset jitter
==============================================================================
*REFCLK(45,0) .IRIG. 0 l 9 16 377 0.000 -0.001 0.001
+REFCLK(45,1) .IRIG. 0 l 8 16 377 0.000 -0.006 0.001
+10.1.4.40 .IRIG. 1 u 22 64 377 0.146 0.024 0.013
-10.1.4.51 0.0.0.0 2 u 48 64 377 1.516 -0.228 0.301
$ ntpq -c peers tock.usno.navy.mil
remote refid st t when poll reach delay offset jitter
==============================================================================
*REFCLK(45,0) .IRIG. 0 l 3 16 377 0.000 -0.001 0.000
+REFCLK(45,1) .IRIG. 0 l 2 16 377 0.000 -0.007 0.000
+10.1.4.40 .IRIG. 1 u 6 64 377 0.116 0.029 0.017
-10.1.4.51 0.0.0.0 2 u 65 64 377 1.467 0.080 0.182
Note that both of their servers prefer to sync off of local hardware
time devices (specifically dedicated hardware with IRIG/AFNOR TCRs in
them).
I'd love if one of their admins could explain what happened, for
educational benefit at bare minimum.
