I want to allow shoppers who have not logged in to keep items in their cart for several hours instead of the default which I believe is 1440 seconds (24 minutes).

I looked at Admin>Config>Sessions and did not see a relevant configuration parameter.
So I also messed with /includes/functions/sessions.php with no success, playing with $SESS_LIFE.
SESSION_TIMEOUT_CATALOG sounds like it might be relevant but doesn't seem to be defined or assigned a value anywhere.
I do not want to changed the admin's login session life . . . just the shoppers' cart's life.
I'm not sure how to do it without messing up or if this is even the right approach to the problem.

Thanks!
