DST definitely isn't helping, but in my experience, DST only makes this stuff more arbitrary, between the winter and the summer here where i live, the sunset can vary up to about 4 hours based on season. Time is entirely arbitrary in relation to the sun to begin with. It's a lived experience that many of us have.

And while we do use things like morning, noon, afternoon, evening, night, and midnight. Those are all relative to the local solar time, not the actual time. Sure noon being at 12 is kind of nice i guess. But noon is noon, the time on the clock doesn't change that.
