we overstep

What do you think about daylight saving time? Daylight saving time is good to save electrical energy and use more sunshine during summer time. Winter time is default but summer could be all year long. During winter it’s dark in the morning and evening so we use 100% of sunshine anyway. Is it unnecessary confussion or it ads some variety?
Who did that decision? everyone just turned their clocks but noone thought that it is our decision, that decision was made years ago and we follow one another.
