Clock constantly resests it's self.

Resets back to 12:00 every time I turn off ignition. The rest of the radio works fine.

Is it a stock radio?

Power runs to a radio from two different sources. One source is through the ignition, (turns radio on and off when your turn truck on and off), and the other runs directly to the battery (keeps time, saves settings, radio stations, etc)

Either you have a short in the constant power source (direct to battery), or when someone hooked up an aftermarket radio they ran both power through ignition or didn't hook up the constant at all.

Best thing is to pull the radio with a test light.

Hope that helps.

For me when this problem showed up it was simply a loose connection at the battery.
