having it like this might confuse the people that use the obviously wrong data format like  MM/DD/YYYY
Having it respecting the system localization (as described partly here trac.xbmc.org/ticket/11981) and then transform it to a universal time notation that is not causing headaches for addon devs would be great.
For password would this be partly in affect? http://trac.xbmc.org/ticket/13636
Note: i never used this dialog before so  don't know current behaviour. The same might apply for TIME (24hour/12hour notation)
