Wow, this day using ubuntu alpha state is really boring. I cannot get updated cause my date isn’t being updated. I mean the developer has developed the Time state, but the forgot to update the date. If you start your PC then their you see the change in date as it is loaded once, but in the panel you cannot see the update of the date. Yesterday, I forgot to close my PC and the same happened to me.
If you want to update the date without restart, you can goto Time & Date Settings. Then unlock the change settings. After that change the date and then close the window. You get the change.
I am using Ubutnu 11.04 Natty Narwhal on 64 bit Laptop.
