Well, I still don't know what caused our time stamp to change but I was reading on the tech boards and they suggest each member adjusts their local time in "my profile" under the preferences tab. I adjusted mine, and my time is back to normal. It was mentioned that if we adjusted the time stamp through the control panel, other problem might occur.
I am not sure what to do with your countdown clocks. Can you reenter your countdown info to make it return to normal? I don't use the clocks so I am not sure what is involved in that and I apologize if it's a pain in the butt to do :(

I am sure John will shed a little more light on this subject when he gets a minute to post.
