Q. I’ve configured BIND named TSIG as documented here. It worked for some time, but my /var/log/messages got the errors as follows:

zone example.org/IN: refresh: failure trying master 71.22.11.22#53 (source 0.0.0.0#0): clocks are unsynchronized: 9 Time(s)
zone example.org/IN: refresh: failure trying master 71.22.11.22#53 (source 71.22.11.22#0): clocks are unsynchronized: 9 Time(s)

How do I fix these errors under Debian Linux 64 bit etch server?
