check time drifting on windows hosts

Hello.
 
Is there a way of checking for time drift on windows hosts (using bbwin) in xymon?  
 
I can see that on linux hosts this is a part of the cpu test, you can see how far off the time is between the monitored host and the xymon server.
 
In my case, the Xymon server is also the NTP source for my company and I want to know if servers are not within around 10-15 seconds from that time.
 
 
best regards,
