Ah, cool, thanks...
The task bar is indeed split into segments, left one is desktop 1, right is desktop 2. It's default with #! (Crunchbang) and the Openbox WM.
I do have a clock in the tray on the right, but I can't be bothered to find the right config file to edit and make it black text instead of white, hence using Conky to display the date and time.
