No, I hadn't.

Thanks -- I know it didn't work if things were too far off, but I didn't
know about ntpdate.

I've done all those things, and checked that my firewall isn't blocking
messages.  Things still don't work.  I have three time servers -- the
closest router to my house (66.25.200.1), ntp.texas.rr.com and
tick.uh.edu in my /etc/ntp.conf file.  Last night I ran ntpdate and
the time was within 1ms of the time servers.  Right now it is 14.7s
off.  The /etc/ntp/drift file =still= says 0.000 (same as always).
