Configuring the Offset-Threshold for
NTP Audit Log
You can configure the system to send an audit log message to a syslog server if the time difference from the
NTP server is greater than a threshold value (offset-threshold). However, time synchronization still occurs. To
configure the offset-threshold, follow this procedure.
Specify the threshold time interval before which the system generates an NTP audit log message if the
system time deviates from the NTP server.
