A clock with a GPS chip and a receiver for getting the official time signal could continuously tweak the length of what it used as the "minute" for user-interface purposes, so that noon would always be when the sun reached its zenith wherever the clock happened to be, and midnight would always be whenever the sun reached its nadir.
It might be less confusing, though, to use degrees instead of hours.
0° — midnight
90° — sunrise
180° — noon
270° — sunset
"I'll meet you in the park at around two-hundred." "Sorry I'm late; I was out drinking until thirty."
If everyone had watches that displayed this sun-based time, train and airplane schedules could just use GMT internally and use the sun-based time when issuing schedules for customers. Of course, that means that the same route would depart and arrive at different times every day of the year, but they do that now anyway, right?
