Date formatting is handled directly by the device, so it can display dates differently for different users based on the region of the world the device is set to.
If you want to hard set that format, you would probably have to use something with the Format Date column (not a100% reliable), or some javascript, or several computed columns to break down the date and put it back together. But first I would look into what you have for region settings in the browser or the device itself, because that will definitely have an effect.
