Report for last seen machines

Question

I'm trying to build a report to show all Serial numbers of machines, machine name, Top console user and when the machine last connected to the domain.
I have the first 3 sorted and working but I don't know what variable i'm looking for when trying to add a last logon.
I did add the additional attribute for the active directory discovery management for last logon but when that runs it gives me some stupid number like 3213201930219312 instead of a date/time.
The query I'm using at the moment is: 
SELECT     dbo.v_R_System_Valid.Netbios_Name0, dbo.v_GS_SYSTEM_CONSOLE_USAGE_MAXGROUP.TopConsoleUser0, dbo.v_GS_SYSTEM_ENCLOSURE.SerialNumber0, 
                      dbo.v_R_System.lastLogon0
FROM         dbo.v_R_System INNER JOIN
                      dbo.v_R_System_Valid ON dbo.v_R_System.ResourceID = dbo.v_R_System_Valid.ResourceID INNER JOIN
                      dbo.v_GS_SYSTEM_CONSOLE_USAGE_MAXGROUP ON dbo.v_R_System.ResourceID = dbo.v_GS_SYSTEM_CONSOLE_USAGE_MAXGROUP.ResourceID INNER JOIN
                      dbo.v_GS_SYSTEM_ENCLOSURE ON dbo.v_R_System.ResourceID = dbo.v_GS_SYSTEM_ENCLOSURE.ResourceID
Any ideas?

So that AD attribute is store in milliseconds (if I remember right) since Jan 1 1970. You will need to convert this to a date time format. The first thing to do is confirm the AD attribute's type and meaning then you should be able to find some query to
convert it into a date and time.
