From my understanding of session, the session will be destroyed if the
browser is closed or the user initiates a command to destroy it. (a
button "log out"). Is there a way to set a time variable on sessions.
Say to 20 minutes of idle time or must a user log out?

When you create the session, add your own variable called
$_SESSION["last_page_load_time"].

if ($_SESSION["last_page_load_time"] < time() - 20 * 60)
{
// don't time out, keep the session going...
$_SESSION["last_page_load_time"] = time();
}
else
{
// delete cookies
// unset session variables
// destroy session
}

The above will completely control the 20-minute window from your end. Not the
best, I'm sure, but it'll work every time.

As a side note, I'd encourage you to read Jeff Atwood's article on sessions.
