We recently received a call from a client asking about a Vtiger Session Timeout Length. Here is the answer for anyone else who is interested:
The Vtiger session time is ultimately controlled by the php system variables. In the apache2 php.ini file. Just vary the number of seconds to get the session length you want. Be sure to restart apache.
Default php value:
session.gc_maxlifetime = 1440
Change to (24 hours)
session.gc_maxlifetime = 86400
