You could add a shutdown command to the root crontab. e.g. if you want the machine to shutdown at midnight you might add:
55 23 * * * /sbin/shutdown -h +5
which will give any users 5 minutes to tidy up.

I'm not sure if the right command is:
sudo crontab -e
or:
sudo crontab -u root -e

For details of what all the fields mean you need to look at:
man 5 crontab
