This is exactly right. especially if you live in a warmer state its more likely to happen. i was looking at an R to buy over a year ago and it had this same problem it was the DIM and the soldering was badIts to do with solder points coming loose/bad contact in the circuit board. Same reason why DIM goes blank etc. Clock failure is just one of many symptoms.
like contrast said. its not the battery its the DIMBattery is good - relatively new AGM. I am not about to take the dash apart just for the clock, so I guess that I will just live with it. Since I usually mount my Droid with blue tooth connection to stereo, the auto display gives good clock readout as well as GPS speed.
Thx for all the replies.
I would check this software update first also -if it's a dim /dash module failure you would have some other gauges doing wacky things also - it is only about 160$ From European electric in Tenenasee for a complete dash module resolder, ( he re-solders everything ) and it's a 5 minute removal / installation very simpleMine has done this for the full 8 years I've owned it. When I asked before, I was told it was a software update that the dealer could do to fix it. I haven't bothered because it isn't that annoying. No DIM failure.
I would check into that first before flinging cash at it in the form of a new DIM. The clock would be much more than just a few minutes fast if the DIM was failing (other posts describe it going like a slot machine).
