You can also shutdown your ubuntu system at specific time using command line

Enter sudo shutdown -h +m OR Enter sudo shutdown –h hh:mm.
Enter your password.
The system will then shut down within the minutes or at the time specified. Shutdown is a GUI program for scheduling a time to shutdown the system. You also have other options to shutdown and halt your running system through time.
-r Requests that the system be rebooted after it has been brought down.
-h Requests that the system be either halted or powered off after it has been brought down.

-P Requests that the system be powered off after it has been brought down.

-k Only send out the warning messages and disable logins, do not actually bring the system down.
even more simple, how about…
sudo shutdown -P 22:00
Does it work better than GShutDown?
