While you are at can you change the date format as well? DD/MM/YYYY instead of MM/DD/YYYY (US). It should go from small to big. The other way around makes my head hurts every time.
The best part of YYYY-MM-DD is that almost nobody uses it, so it'll be easier to get everybody to support. I don't think we can standardize in either DD-MM-YYYY or MM-DD-YYYY.
