Yeah, I would almost bet that this is a software glitch in the COMMAND (similar to the Y2K bug, or the upcoming GPS "week number" bug which will hit on April 6th) and that *every* W221 has it. But of course people only notice it when either you had disconnected your battery or when for some reason the analog clock is off by that much that you want to adjust it. I'm sure over time more and more W221 owners will notice. Will MB do anything about it? I don't think so, the car is out of warranty for a long time, so why should they bother.

GPS "rolls over" to 0 tonight at midnight. Let's see how that affects this issue!

Update: It's not fixed! It still resets to one day past yesterday, August 22, 2003...

If your clock is still not adjusting after the Week Number rollover (this appears to have fixed many NTG3s based on reports) the MBUSA recommended method is to set the time in COMAND and reset the Instrument Cluster via Star Diagnosis, or you could alternatively remove and reinsert the fuse, which is locate in the Front SAM under the hood. I don't have the fuse number handy, but IIRC, there are two fuses that are related to the IC.

I believe the two fuses are #25 and #39. However, this didn't fix the issue for me in my 2007 CL600. Analog clock reset to 12:00, date still won't "take".

UPDATE: This morning I got into the car, quickly hit the START button once, and set the time via COMMAND menus. This time, the analog clock adjusted to the COMMAND time! Yahoo!! Of course, it will be interesting to see if the fix stays overnight. FYI, I'm parking outside overnight. The DATE is still wrong, but it may have been that I ran out of time. I might try again tomorrow morning, but I don't want to push my luck.
