How do you set a digital clock on Mitsubishi Magna 2003?

Is that a model with the time in the radio, or is it above the centre air vents?

Owner's manual (if still available) are/were cheap from dealerships.

I can explain how to do it, if you say where the 'time/clock' is.

OK, next to your speedo cluster there are 3 small buttons, 2 arrows and one bar. Press the bar and the arrow "up" at the same time to switch the ODO off, then just use the the up and down arrows to adjust the time. Hold them down to suit the time you want. After you have done than, hold the bar then arrow "up" again to switch the ODO on.

Hope this helps... if not, let me know!
