I don't think it has. The nearest I can find is that if you use System.getProperties you get user.country which corresponds to UK in my case. You can try changing that; of course if I change that to "FR" my computer will spend the next week trying to feed me snails and frogs and saying "pas manger le rosbif" (Don't eat roast beef)
So you will have to remember to change it back afterwards.
There are bound to be other similar properties elsewhere. Somebody else will doubtless know something sensible.

On another recent thread I noticed the getDateInstance method takes a Locale as a parameter, so that sounds more promising.
