                <div>We have an IPSEC peer that keeps dropping the
                  tunnel and renegotiating. The only events in the logs
                  on their side that look like they could be related are
                  a fairly constant NTP update which is causing their
                  Netscreen to adjust by between 3 and 13 milliseconds
                  every ten minutes.  Would this cause the tunnel to
                  renegotiate when the clock changed?  It seems to
                  happen on the half hour every half hour, or every
                  three NTP updates.</div>
