This is why I've always advocated for two times. One based on what you want (constant intervals of time), and one based on the position of the sun as a percentage or similar. We can go to town with the complexity of the latter, but the former should be kept as simple as possible like you say.

Even for a small mobile phone screen?
Anything cut to length will be too short.
