Would someone care to explain why my refclocks always look like
this?

oPPS(0)          .PPS.            0 l   64   64   37    0.000    0.134   0.057
+ULINK_M325E(0)  .WWVB.           0 l   63   64  377    0.000   -8.680   0.049
  LOCAL(0)        LOCAL(0)        10 l   58   64  377    0.000    0.000   0.001

Assume for the sake of argument that the other stratum 1 servers agree
with the WWVB clock, and that my ntp.conf is

#
server  127.127.22.0
fudge   127.127.22.0 flag2 0 flag3 1
#
server  127.127.34.0 prefer
fudge   127.127.34.0 flag1 0
#
server  127.127.1.0
fudge   127.127.1.0 stratum 10

plus public servers.

Attempting to fix the gap by fudging (time1) fails to align these.
