This was actually answered, but just to make sure...  when you log into
a box, it makes an entry into the /var/run/utmp (may be different on
different distributions).  When you log out, another entry is made.  If
you do not log out, but lose your connection, this will cause the logout
entry to be not registered.  Also you can have your shell still running
at times, if it did not receive the proper signal.  This can also
traverse reboots since the logout entry will still not exist (not the
shell still running). 

utmp (and wtmp, the backup usually located in /var/log) contain info
also used by the 'last' command to say when people were logged in and
how long they were on and other bits of info like when the machine was
rebooted (and the kernel version often).  I prefer 'w 'to 'who', as it
adds some more info about the idle time and what they are running by
default, but it still relies on the utmp file.
