Check manual page of systemtime
|Synchronization of Operating System Time|
|Distribution||official part of Check_MK|
Its advantage - however - is that it works on any Windows host (with an agent of version of 1.1.10 or later) - regardless of the method used to synchronize the time.
Levels can be set for making the check warn/crit if the time difference exceeds the configured limits.
One service is created for each host supporting this check. Currently this is the windows agent in version 1.1.10 or later.
