I really like the 24h sun widget on my Instinct Solar display. However, it isn't really totally logical for the night part.
In the current implementation, at 24 / 0 hours / midnight, the sun is always at '6 o'clock', thus at the bottom. Basically, what it should do, in my humble opinion, is to simply split the day into two separate moving speeds for the sun, i.e. dawn till dusk, and dusk till dawn. Instead, here, it basically separates day and night into three parts, one for day and two for night.
I can't really understand the logic behind this.
