You're aware that Winter time is the 'standard time', and that you won't get more light hours by moving the clock around right? The sun is rising at around 07:00 and sets at around 16:30 in November in Berlin, getting up at around 7am isn't too hard to make most of the sunlight (personally I find it more depressing to get up in the dark then ending the day in the dark tbh). The only way to get more light out of a winter day in Germany is moving further to the south.
