World clock face colour (black or white)
The clock face colour confuses me. For example, does a black 5.30 mean AM or PM? In winter it can be dark at both those times. Does it mean AM or PM? Or if night or day, how are these defined? There's an old thread which doesn't have a satisfactory, referenced answer, and I can's find an Apple explanation.
