This seems to ignore latitude shifts through the year. Why should solar days affect your day? I'm quite OK to wake up at 8am in the dark, and not so much at 4.30am in light. We were not all born on the equator.

If you set your alarm for 2.80 you'll wake at the same time whether it's dark or light. Or perhaps I've misunderstood your objection?

Anyway the numeric value is the same everywhere so it doesn't affect your time, it just affects the way your clock face is drawn.
