Decimal time doesn’t seem as useful to me as localized time. With GPS coordinates, we don’t need a timezone system, everybody could have noon at solar noon. When setting up meetings, one only needs to include the longitude and everybody could easily join at the correct time. It would be cool if airplane rides showed a real local time while in flight. Might be a cool app.
While we’re at it, the Gregorian calendar could be made celestial as well. Date could be based on the solstice/equinox and moon. Apparently this is called a lunisolar calendar and repeats on the Metonic cycle every 19 years. Though it’s off by a couple hours. That means if I recorded a message with lunisolar date and local time, a historian could probably infer the exact year it was recorded.
