Last Contact time for a PC and Lenght of Time on-line afterwards

Last Contact time for a PC and Lenght of Time on-line afterwards

I know how to obtain the Last Contact time in Scope of Management.  I have not found the Last Contact Time listed for automated reports (Last Scan Time is listed). 
 
Is it possible to add Last Contact Time to the list so I can produce a report that lists both the Last Scan Time (I interpret this as meaning Last "Successful" Scan Time) and Last Contact Time?
 
Also,  does DC keep track of when a PC initially connects and how long it stays connected?  I have a few sites that may have network issues and this may help me identifiy them.
 
Thanks
