Editor: If you need to shut down your computer automatically at a given time, you can use Terminator to do this for you. For instance when your computer has burned a CD, recorded some TV or radio show without your surveillance, Terminator will do this for you.
If you use the Autostart folder to launch Terminator automatically, you can use a startup parameter to set the shutdown time: with the following command, Terminator would close down Windows on December, 24 2002 at 3:24 P.M. and 44 seconds: C:/Programs/Terminator.exe "24.12.2002 15:24:44"
