Are you driving at 3.8 x 10^8 m/s?

 

I have noticed that the clock in the instrument panel showes a different time then the clock on the PCM display. Has anyone else noticed this?

 

This sugject has been discussed earlier. I recall others mentioning that having the navigation system in the car eliminated the problem as the car's clock would get updated as needed from the GPS. Many years ago the clocks in the 911 models were the most accurate things around. What happened? I absolutely NEVER had to manually intervene on those to reset them.

My previous Benz had this problem. Solution was to replace the entire instrument cluster. I was afraid that they would introduce rattles if they did this and so I never took it in. On the other hand my Rolex (never serviced) has been running fast for 5 years. If I average the car and clock and Rolex I get a good approximation to the correct time.

Have the same problem with my non-nav 997. (and the same solution).

 

For another 6000 dollars yuo can get the "accurate clock" upgrade from the a hole's at Porsh.....................

Mine clock was always off by a couple minutes as well .....

 

That's odd--in my Club Coupe the clock and PCM display always display the same time. And like others, mine loses time. I keep my car hooked up to the Porsche charg-o-mat (battery tender), so it's not the battery losing charge between start ups.

Mildly irritating--the clocks on my 5 previous Porsches (all from the 9X6 generation) never lost time. They stayed very accurate.

 

yeah, that is odd. my two clocks are the same. the PCM switches about 1/2 second before the OBC
