bad timing

Previously, I had my fileserver sync time with my primary wireless router and some pool.ntp.org servers. Then I noticed this:

Jul  7 08:41:10 remote  /usr/sbin/ntpd[521]: skew change 255.181 exceeds limit
Jul  7 08:56:48 remote  /usr/sbin/ntpd[521]: skew change -34.707 exceeds limit
Jul  7 09:24:28 remote  /usr/sbin/ntpd[521]: adjusting local clock by -0.159868s
Jul  7 09:24:28 remote  /usr/sbin/ntpd[521]: skew change -32.121 exceeds limit
Jul  7 09:39:06 remote  /usr/sbin/ntpd[521]: adjusting local clock by 0.465410s
Jul  7 09:39:06 remote  /usr/sbin/ntpd[521]: skew change 132.634 exceeds limit
Jul  7 09:44:23 remote  /usr/sbin/ntpd[521]: adjusting local clock by 0.727679s

According to the documentation, there's no real-time clock on most OpenWrt compatible hardware. I guess when you consider the minimalistic setup of these devices, you can't expect everything.

I've now switched it around. My routers now sync with my fileserver and us.pool.ntp.org. My fileserver ignores the access points and syncs with:

server timex.cs.columbia.edu
server ntp-2.cso.uiuc.edu
server ntppub.tamu.edu
server ntp-1.vt.edu
server ntp3.cs.wisc.edu
server 0.pool.ntp.org
server 1.north-america.pool.ntp.org
server 2.us.pool.ntp.org

Those are the same NTP servers I use at work, with 3 pool.ntp.org servers thrown in. It just annoys me that OpenNTPD doesn't have the equivalent of "ntpq -p" to check the status of the NTP sync.
