You can set your clock back a minute every minute from cron using the "date" command. Try: date -s "now - 1 minute" If that's not good enough, you can write a loop that resets your clock back a second every second, again using the "date" command. while true do date -s "now - 1 second" sleep 1 done That should make time appear to stand still at the HH:MM:SS level. Another possible method is to pause time itself. However your computer won't work any more, and will remain frozen without any changes. HTH, Aleksey
