Count down until shutdown on dialog not showing

[Wise Melon]

I am running Ubuntu Gnome 15.04 (with Gnome 3.14) and I have noticed that the dialog which asks you if you want to "Cancel", "Restart", or "Shutdown", tells you that if you do not select an option within a specified length of time, the machine will automatically shutdown. However it would be more useful if this could actually also act as a count down to tell you how much time you actually have left before the machine automatically shutdown.

This has been implemented for a long time, are you sure its not working? Note it only updates every 10 secs, until the final 10secs, then it counts down per second.

Yes, I have sat there watching it for the whole time, it never counts down.

Is the logout dialog also affected?

[Wise Melon (wise-melon-deactivatedaccount)]

Yes it is.

Oh dear... Well this is a little bit embarrassing... It turns out that it is not a bug in the program... But in fact a speck of dust on my screen... Now that I have removed the speck of dust off my screen, I can see the count down counting down...
