Idle time is shown as: If a user has not typed to the system for a minute or more, reports this as idle time. If a user has not typed to the system for an hour or more, the user is omitted from output unless the flag is given. An example output line from would look similar to: This output line could be interpreted as is logged into and his terminal line is has been logged on since September 12 at 13:28 (1:28 p.m.). has not typed anything into for 11 minutes.
