my 2002 c5 clock keeps reseting to 8:15
my 02 c5 only has 16,000 miles i keep a battery tender on it but this year every time i use it the clock resets to 8:13, i reset it, drive it but the next time i get in it's back to 8:13, my battery is about 6 or 8 years old i was going to change it and see if this solves the problem
