First, see the explanation of the CLOCK setting in the analysis.cfg 
man-page.

The client inserts a timestamp in the client message, usually just 
before it transmits the message to the Xymon server (not sure if that is 
the case with BBWin, though - it might add the timestamp when it begins 
collecting data, which could explain it if the eventlog scanning takes a 
long time). This timestamp is then compared with the time that Xymon 
receives the message. In your case, they are 138 seconds different.
