What's wrong with 10/11/12 ?

I am not sure i understand your email/problem.

As far as i read this email your concern is:
 * localized dates use the locale date format
 * locale date format is "wrong".

So the two options are:
 a) User changes their locale
 b) Apps don't use localized dates and use a custom format.

Am I understanding your email correctly?
