That's why my time system https://kybernetikos.github.io/UIT/ rotates the clock depending on your GPS location. The idea is that the numeric time is the same anywhere in the world but your clock is displayed with solar midday directly up and solar midnight directly down.

It explicitly intends that each solar day is split into 10 which is then subdivided into 100 and then again. This makes an ergonomic system for human usage although the fact that its time periods vary according to the day mean its not appropriate for science and engineering where consistency and accuracy are more important.

Doing away with time zones means arranging international meetings and travel is easier. Putting a full day on one click face lets you draw on the sun rise and set times and also lets you draw a days worth of appointments on the face. Since it's base ten addition and subtraction are trivial.

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.
