Adding the year to file properties in openSUSE 11.1

Is there a way to add the year a document or file was created and/or modified to the details shown under its Properties? As it stands right now in my openSUSE 11.1 I get the date (without the year) and the time of creation and last modification, that's it. I work with many older documents and I need to know the year they were created/modified. Thank you!
