I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

There is no direct GPO but it's possible via a scheduled task item which you can create via a GPO.
You can schedule the task to run a program called
At the specified time.
With the following parameters
/l /f

This will logoff the user and also close any unsaved work.
If you do not use the "/f" option or use "logoff.exe" any unsaved work will prevent the logoff to succeed.
That will logoff the account that starts the task. So you would have to have to deploy it as a user task, not a computer policy.

Refer the link, which will give detail steps for configuring the schedule task , also it list the steps to trigeer a logoff message before it logoff the system.

Indeed as an "User Configuration" GPO
My suggestion was at least in the right direction but anyway...
The article is using logoff.exe and this won't force the logoff if the user has unsaved work as already mentioned.
