ntpd: adjusting local clock, but it doesn't

Hi misc@,

This may actually be a bug -- it's just so odd that I wanted to run it
by here first.

Running a syspatched 7.8 (amd64) on a Xeon E5-2650 v2.

Clock is off, ntpd tries to correct it, but it never does.

Here's an example:

Dec 29 05:19:23 myhost ntpd[50297]: adjusting local clock by 519.109281s
Dec 29 05:20:27 myhost ntpd[50297]: adjusting local clock by 518.792356s

Right after it adjusts the local clock, I check, and it's still 518~
seconds behind.

This was with a stock ntpd config, and with one that I changed to use a
local ntpd server.

Am I doing something wrong?

Thank you!
