I don't want to hibernate, that just sounds like depression, but if someone wants to argue that I'm sleeping too late by waiting for the crack of dawn to actually happen, I feel I've got a leg to stand on in that argument.
Also, from an entirely selfish person point of view, the sunrise lines up with my commute exactly in the dead of winter, and I drive south to work, which means driving right into the sun. Moving clocks an hour at that time of year would put the region where I'm driving at exact sunrise at times of year when the sun doesn't rise as far south.
