[chrony-users] High skew values

[Arnon Weinberg <arnon@xxxxxxxxxxxxx>]

chrony is not setting the time.

/var/log/messages contains many of the following type of entries:
chronyd[490]: System clock wrong by 15.124741 seconds, adjustment started
chronyd[490]: Can't synchronise: no majority

Additionally, chronyc -> sourcestats shows very high skew:

chronyc> sourcestats
210 Number of sources = 4
Name/IP Address            NP  NR  Span  Frequency  Freq Skew  Offset  Std Dev
==============================================================================
S0106bcaec5c4f690.vc.shaw   4   3     7 -68474.500     479381  -119.5s    84ms
zeit.rcloran.net            4   3     7 -58189.289     471160  -101.5s    59ms
ox.eicat.ca                 4   3     6 -81081.703     354399  -141.5s    48ms
mirror.mountaincable.net    4   3     7 -49499.297     381278   -86.3s    46ms

I interpret this to indicate very high network latency, but the network is fine:
>ping zeit.rcloran.net
--- zeit.rcloran.net ping statistics ---
5 packets transmitted, 5 received, 0% packet loss, time 4021ms
rtt min/avg/max/mdev = 0.386/19.406/26.854/9.787 ms
>ping ox.eicat.ca
--- ox.eicat.ca ping statistics ---
5 packets transmitted, 5 received, 0% packet loss, time 4058ms
rtt min/avg/max/mdev = 0.314/1.326/1.777/0.568 ms
>ping mirror.mountaincable.net
--- mirror.mountaincable.net ping statistics ---
5 packets transmitted, 5 received, 0% packet loss, time 4021ms
rtt min/avg/max/mdev = 3.527/3.763/4.032/0.174 ms

So stumped now.  Why might the skew be so high?
