I've had my car for about 2 1/2 months now, and I love it!
The only problem is the clock falls behind about twenty minutes!! The first time happened about a month ago, which I just re-adjusted it hoping it wouldn't happen again, but it did two days ago! Any suggestions?? What does this mean??

 

Sounds like you are not the only one having this problem on the 3. Think I have seen a similar thread in the 6 postings but was not able to find it.

if the car is still under warranty you can take it to the dealer and will replace the clock module or radio..depending on the radio

 

Several people here in Australia have reported a similar problem!

Get it checked by you dealer and get it fixed under warrenty!
