This usercontrol uses by default the system's Regional settings, but you can change these values to suit your needs. This usercontrol comes with a nice demo program allowing you to experiment. Extensively documented. In my view a must for those interested in local settings but who never investigated the issue or got discouraged by the documentation ;)
