Somebody in the thread at some point said:

No I think that is normal: I see it here.  I was kind of hoping ntpd
would drop dead in an interesting way.  This one is also seen here
(lines 234 and 1167):

adjtimex({modes=ADJ_OFFSET|ADJ_FREQUENCY, offset=0, freq=0, maxerror=16,
esterror=16, status=STA_UNSYNC, constant=4, precision=1,
tolerance=33554432, time={1189246336, 574721}, tick=10000, ppsfreq=0,
jitter=0, shift=0, stabil=0, jitcnt=0, calcnt=0, errcnt=0, stbcnt=0}) =
5 (TIME_ERROR)

However, what isn't seen here (where ntpd works) is ipv6 support.  You
appear to have it enabled

1228: open("/proc/net/if_inet6", O_RDONLY)    = 5

whereas I have it turned off

open("/proc/net/if_inet6", O_RDONLY)    = -1 ENOENT (No such file or
directory)

If you want to look at killing it, add this to /etc/modprobe.conf

install ipv6 /bin/true

and reboot.
