Get rid of political time-zones and DST and simply define 6:00am to be sunrise world wide. Each day starts at 6am and counts from there.

(If you are really brave let the length of the hour vary by latitude so that sunset is always at 6pm as well. In the winter up north the night hours are simply longer than the daylight hours. But this is too enlightened I think.)

We have the tech to do this. The first one is very practical. What time is it? How many hours since sunrise in this location +6?

@futurebird Nobody ever buys it, but I still think this is the way to go: https://around.com/time-for-earth-time/
Time for Earth Time - James Gleick

The time has come to deep-six not just Daylight Saving Time but the whole jury-rigged scheme of time zones that has ruled the world’s clocks for the last century and a half.

I find the idea of single, all-earth timezone enormously tempting, and it would certainly solve a great many time-related computer problems. And I think most people who regularly work with someone in who lives in another timezone could probably be convinced to support the idea. I don't know if that would be enough to get the idea taken seriously, however.
