Run a tcpdump on an upstream machine and restart ntpd on the offending
system. Verify that the noise really is from your system. Verify that
ntp traffic can return through your firewall. Try manually setting the
hardware clock to the correct time with the following:

/usr/bin/rdate -s ntp1.csx.cam.ac.uk && /sbin/hwclock --systohc --utc

**NOTE** my hardware clock is set to UTC not localtime. That line will
set the system time based on the time at the ntp1 system in the UK
(there are other rdate servers) and then set the hardware clock based on
system time.
