Pixies......If anyone ever finds out what the hell happened I would love to know the answer.
AlfieThis is a bug that affects the W221 S and W216 CL. We had two cars in this week for the same issue. Loading the latest firmware doesnt resolve it either.
There isnt a fix (yet). Dont waste your money asking the dealer to look at it. they will tell you they cant fix it and here is a bill!
Just checked mine and yes it had changed to November 10th. Time was still one hour fast - i.e still on summer time. Went into the time zone menus and the tick option for auto summer/winter time was not showing - it had 2 options for either standard time or summertime. As summer time was selected I changed it to Standard time and the time corrected on the Comand Screen but did not update the analogue clock. Went back to check the date and its gone back to March 27th 2018 and I can alter it?? Also the tick option is back for summer/winter time but changing does not alter the time??Had the same problem on My 2007 S500 & wife's 2006 S350. Persisted with resetting attempts to change date in Command/Vehicle/System - Time & Date since BST ended; all with zero success. It always reverted to a date in March 2018.
Got both cars out this morning and was about to disconnect the service battery to power down the systems to reset but decided to check date/time before doing it - to find both cars had changed overnight to show the correct day. I hate technical mysteries so has anyone got an explanation?
Change the time zone and see if your date goes back to March like mineOh god I'm reluctant to look at mine again
Not just W221s. R230s have issues as well - some will only show the date as 1999 (which is before they were even made).Just checked mine and yes it had changed to November 10th.

My car is booked into a main dealer on 22nd November so i will show them this post when I take it in but it seems clear to me its a bug affecting all the W221'S like Alfie said
If it were a satellite problem every device on the planet that uses GPS time would be affected.guess what, went to mine this morning and yep it's gone back to march!! I think it's the Russians buggering about in cyber space.
This has to be a satellite problem.
Change the time zone and see if your date goes back to March like mine
if it's a mistake in the software is it going to be possible that a software update will cure it ?

As Botus says its highly unlikely MB will feel the need to fix it no matter how simple it is.
Is it a safety issue? No.
Is it going to cost them money to do nothing? No.
Will most people even notice? No.
Net result Will they fix it? No.
