[Zope] Calculating how long time a user spends on a page

[Gitte Wange]

Hello,

I need to find out how long time a user spend on a page in my zope site.
Guess you can do that by a session/cookie, but I don't know anything about it.
Anyone who has tried to do something like this ?

It's for a cinema that plays movies (pay-per-view), so I need to count the 
minutes from the movie begins to the user exits.

Any good ideas ?

Regards,
