No i can't tell on the drop of a hat; that's what your favorite $LIBRARY is for. If you need to know something, research. If you don't want to resort to the terminal, please show me one mobile OS that supports you in doing this (cherry-picking various parts from regional settings). Hint: Not even most of the true Desktops OS do it.

(If one would to, it could be possible to read your post as "i am too lazy to look it up by myself even if this would allow me to set it up the way i want it as an outcome, so someone else should implement a nanny-GUI for it.")
