That probably would work well for those closer to the equator.

But for those in the 100 minutes zone of this map that would mean going to work at 6:30am in the summer (assuming we are using civil twilight as “sunrise”), and 9:30AM in the winter which is much more of a swing than daylight savings puts on us, but at least it is a gradual one.

For those above the Arctic Circle, they just work 24/7 for a couple of weeks in the summer but get a similar time off in the winter ;)
