As Paul says, the upload date/time is present all the time, but is hidden if you have the sidebar displayed. So you need to close the sidebar to see upload times. TBH it's not the cleverest piece of UI design - would be better if the top of the sidebar panel started below the menu line.
I think your layout should be remembered from one session to the next, eg if you prefer the sidebar closed - it's only if you need to make some adjustment to your account or settings that you need the sidebar open.
Also IIRC the date/time does turn red if the uploads stop, ie same behaviour as in 1.0.
