I'm applying tags to a set of recorded data files, and I have to classify by when the recording appears to be taken (if it's light or dark).
TimeOfDay: Day
TimeOfDay: Night
TimeOfDay: Dusk
TimeOfDay: Dawn
TimeOfDay: Night/Day # (the recording spans both Day and Night)
Is there another term to describe "time of day"?
Edit: As per the comments, removed most of the specific constraints - question now focuses on the terminology.
