It's not possible to tell the amount of time user spends on a site with any tool - 
HTTP is stateless, and there's no way for you to tell whether I spend 45 seconds or 45 
minutes to read a page on your site.

Webtrends is more than happy to tell you whatever you want to hear if you hand them 
large amounts of cash. Whether you should believe them is another matter entirely, but 
obviously, if you've paid them all that money, it's much easier to convince yourself 
to believe them than it is to ignore them.

And there's the magic word - "assumed".

You could consider making it up - if it makes him feel good, and it's what he wants to 
hear.....

On the other hand, you could ask him what it is he really wants to know. What does he 
expect that information to tell him about his site? What decisions will he make based 
on that information. If he knows what questions he expects to answer with that 
information, then there may be a way to answer the question with the data that is 
actually in the log files.

Having said all that, if your web servers support "sessions" (ASP sessions on IIS, for 
example), you could consider logging cookies, and using the ASPSESSIONID cookie as a 
User, for example, and display the First and Last Date/Time columns in the User 
report. But you'd be far better off using the OnSessionStart and OnSessionEnd events 
in your application to log this kind of information to a separate Log file, rather 
than trying to get it from your log files.
