How to change clock time

Couple of buttons, to the right of the display, think the top one does hours.

Mine hasn't got buttons on display.... Am I missing something? Or is the renaultsport monitor different?
 
mine doesn't either mate (2011 200) i had to change my time thru the settings on my stereo.


add: i don't have renaultsport monitor either
 
Aaaah mission accomplished, I totally lost what I was doing and refuse to read instructions lol
