I would like to know your motivation. We shouldn't all change our clocks so that the sun is overhead at 1:00 unless there's a good reason. I suggest that if you like the sun to be up for more of your waking day, that the best solution is for you to wake up an hour earlier, and go to bed an hour earlier. It is exactly equivalent, except for the numbers that show up on your watch...which you could just set forward on your own if the numbers are the thing you're looking for.
