Is that the date created or the date modified? what does it say at the top of that menu?
Try right clicking>properties>details/attributes and see if the date created is listed as 2011 as LoyceV said.
The 0 balance is probably due to your wallet not syncing yet, how far is it behind?
1. If you click File>receiving addresses is there an address listed there (should begin with a 1 in the table) - just as a test for whether the wallet file is corrupted or not.
2. In the bottom right of the screen is there a closed padlock?
