It should do it on its on the only time u need to mess with ur clock is when u travel to different time zones Then u go to ur settings hit date and time settings and choose what ever time zone u are in. Example I live central time zone but if I went to the east coast I would have to change it to eastern time zone setting. Or if u were to travel to say las Vegas from Texas or louisiana they have a different time zone thats two hours early there than it is here.(not sure what zone it is lol)
