If you object to daylight time year around, and please read the finding how unhealthy it is

37. I've got some ideas about a more natural time system.

Local domestic time could be measured as "hours from sunrise." Phone apps could keep track of this. For example the school day might start three hours after sunrise. A farmer might get out of bed an hour before sunrise. A simple microprocessor can calculate sunrise. That's something the first clockmakers didn't have. There are some good sunrise calculators on the internet if anyone want to get a feeling for how that might work.

Sunrise-to-sunrise times are not consistent throughout the year but so what? That's the way humans lived before clocks were common. Time followed the sun.

Coordinated Universal Time (UTC) would be used for work where the variable length of time from sunrise to sunrise would confuse things. Railroads and airlines would use UTC, hospitals and other 24/7 workplaces would use UTC, etc. If some event of worldwide interest was scheduled for a particular UTC time, perhaps an important football match or a moon landing, the UTC time and date would be advertised and nobody would be confused.
