AD Time Skew Monitor. This monitor generates an alert when the time difference between a domain controller and its time source exceeds a specified threshold.
This means that two domain controller disagree about the current time. If the time skew grows too large, Kerberos authentication can be affected.
Interval (sec) default 300.
Time Source used for clock comparison. If no time source is specified, a time source will be chosen automatically using Active Directory.
Number of Sample default 5. Number of times the threshold has to be exceeded before an alert is raised.
Threshold Warning (sec) default 5. Time skew threshold for warning.
Threshold Error (sec) default 15. Time skew threshold for error.
