Sorry for the delayed reply. Sometimes life gets in the way until it doesn't and those left behind have to deal with it. Anyway...
My clock function did come back on a limited basis. I can manually set the clock and all is well but the displayed GPS clock is approximately 21 minutes ahead of the correct time. The nav display shows GPS is acquired so the GPS is not trying to reset the clock. Not yet anyway.
The date group shows Monday, January 01, 2001. It hasn't changed from the last two days.
Car is a 2008, 3LT, factory everything in the audio/nav system.
I'll be waiting for April 6 for anything else to happen.

Add one more. Dealer replaced the battery yesterday and now - no clock. Also no date. 2010 GS OEM.
Great work setting up this thread. I will call GM and add my complaint to the non-list.

I just got back from local Chevy dealer time wasted. I spoke with the service manager who knew nothing about what I was explaining to him. I mentioned about 600 posts on Corvette Forum regarding clock issues with C6 (never heard of forum). He suggested diagnostic test $150 but if it didn't show anything i'm still on the hook for the teats. He then called in one of his corvette experts and hold on. This genius told me to disconnect the battery hold the positive and negative cables together for 30 seconds and maybe that will work. Needles to say i'm not doing that as my GPS works even though I have the dreaded red slash.
On to start calling GM I can be relentless and also Better Business Bureau. If everyone with this problem bombards them maybe a fix will come along.
Good Luck to all of us.

Thought this article might be of interest to this topic. Kinda contradicts some of the comments about 'maybe' our clocks will magically start working 4/6. But, does support that 2010+ nav won't be impacted. Article indicates what many of us have been thinking - our system needs a Firmware update!

The TSB is posted somewhere in this long thread. BBB will not help you. They told me my car was old and out of warranty, and that all they deal with is new cars and lemon laws in their auto program.

A bit of good news today at last. We don't have to toggle the "Daylight Savings" button inside the clock setup screen as we normally have to twice a year - an advantage of the clock not working at all.

No Clock
I disconnected the battery on my 09 Z06 Yesterday to replace the left door lock actuator. Reconnect the battery, re-index the windows. Everything works except the clock. Adjustment features on the display are grayed out. Is there any new news?

mine came back this morning wrong time and date 12/31/2000. I am sure this was a coincidence this all happened after i dropped my keybfob and pieces went all over. I could not find the battery but carry a spare with me . I put it in and started car and there was the clock.

'07 C6 Clock won't display
After changing the battery, the clock no longer displays and cannot be set with the directions in the Nav manual. This seems to be a software/computer problem.
