I cannot remember/find anything with a timer. The
attached image
settings turns my PC off when I click Log Out. With Confirm Logout
selected I also have to hit enter (or click an option), but no
timer.
In your image you have selected turn off computer. Change it to end
current session. Then with the already deselected confirm logout
you'll have your session quickly ended without any substantial delay.
Changing it would be pointless, it does what I want with no delay or
timer - even when Confirm Logout selected.
