To install it, open the Extras folder and drag the IdleTime icon into your System Folder and restart your Macintosh. To call the idleTime INIT, we've provided a glue script called clock.idleTime. The script is pre-installed in Frontier.root. It returns the number of seconds of inactivity on the system. For example, you could install an agent script that starts a backup after an hour of inactivity.
Any activity resets the idle value to zero.
Things that count are keystrokes, disk insertions, mouse movement or mouse clicks. There's a DocServer page for clock.idleTime .
