How does Operations Monitor calculate the "Session Finish" value?

[#1]

Hi,

I have pulled in the session data from the Operations Monitor App into an app for our Sales team and I need to give them a definition for Session Duration.

Does anyone know how the Operations Monitor calculates the session end date and time value?

Thanks,

Dave

It may serve to validate the log file and process it, should come the start of session and end.
