Online or Offline status

Question

I love the way the Adobe Forum is structured where you can
see if a user is online or offline. I wish to produce the same
method. I have a list of users in my admin page where I see the...
Username | First Name | Last Name | E-mail
I wish to make a fifth column called status that would have
online or offline such as...
Username | First Name | Last Name | E-mail | Status |
MySQL statement looks as such...
CREATE TABLE `adminusers` (
`userID` int(11) NOT NULL auto_increment,
`userName` varchar(50) NOT NULL default '',
`userPassword` varchar(50) NOT NULL default '',
`emailAddress` varchar(50) NOT NULL default '',
`firstName` varchar(50) NOT NULL default '',
`lastName` varchar(50) NOT NULL default '',
`date` timestamp NOT NULL default CURRENT_TIMESTAMP,
`userTypeID` int(11) NOT NULL default '3',
PRIMARY KEY (`userID`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
I believe that the online/offiline status is a boolean
statement but I am not sure and do not know how to incorporate it.
Can someone help me what I must do. Thank you all for your
help.

There is no way that you can tell whether someone is online.
The web is
stateless. All that Adobe is doing is taking an arbitrary
time since
that individual either logged in or last clicked a link. It's
done by
updating a timestamp each time the visitor clicks a link.
Online or
offline status is determined by the time elapsed since the
last activity
(usually 5 or 10 minutes).
