You'll have to change the clock of your G35 whenever the power supply is disconnected, or twice a year for daylight savings time. Fortunately, the clock has a simple, traditional two-hand face and is easily adjusted. The clock to the global positioning device (GPS) is similarly easy to change.
Locate the adjusting knob on the right side of the clock face. It lies right next to the "3."
Turn the knob clockwise to adjust the time forward.
Turn the knob counterclockwise to turn the clock hands counterclockwise.
