Clock Won't Set Properly, Can Set It To Correct Time And It Will Reset Incorrect

followed Manuel instructions to reset clock, I can reset it to the correct time and it will hold at the time for about two minutes before reverting back to the original incorrect time. It does this with out turning the vehicle off. I have reset it at least 50 times in the last week alone. Help!!

This may be a result of a loose connection. I would recommend (if you haven't already), to bring it in to a service technician so they can proceed with repairs.
