E46 clock change

[Tim330]

Hello
Can anyone tell me how to change the clock on my car? I have tried pressing a combination of buttons on the radio and steering wheel without success. Is the clock on the trip computer the same as the clock on the radio? I'm running an hour ahead at the moment!

Thanks in advance

With the time displayed on the computer, twist the small knob on the right hand side of the speedo/rev counter binnacle.

Not obvious, I agree.
