Question on timing

I have a question on how pulse monitors the time. I had an incident
where the application we had rolled this morning. I had noticed that
ntpd was down on a machine and restarted that. It adjust the clock
forward by two minutes. Shortly after that, the monitoring box
considered the master dead and rolled. Could this have been caused by
the time shift forward two minutes. The deadtime in the lvs.conf file is
30. Does this mean that if ntpd shifts the clock forward by more than
thirty seconds it will cause the monitoring box to declare the live box
dead even though it is still alive?
TIA,
Ed
