I have delayed sleep phase and no amount of sleep hygeine (both valid and crazy hyppie nonsense) has helped. All the suplements in the world didn't help. I've done it all, no screens, special bulbs in my lamps, all of it. My therapist told me my only option was sleep medication or just finding a job that would let me use my natural waking time of 9 am.
I managed the later and my life is amazing. I get a full 8 hours of sleep every night. The best way to explain my sleep schedule is count off 5 hours from sunset, that's about when I start to feel tired. Count off 9 hours from there, that's when I'll probably wake up.
Summer is pretty obnoxious with how late I get to sleep. Winters I can maintain an almost normal schedule.
It probably makes sense that we evolved a variety of offsets (both late sleepers and obnoxiously early risers) for our circadian cycles. It creates a natural subset of tribe members that are alert during some of the natural sleeping hours of the majority. The fact that such owls are more mentally stimulated or creative might be selecting for skills that were productive during the dark hours and furthered survival such as repairing or improving hunting weapons, baskets, and the like.
As we've outgrown most of our survival pressures, it'd make sense for those genetic minorities to be more freely distributed and for the circadian rhythms of the population at large to drift and become more mixed since it no longer matters if a majority of your "tribe" has a suboptimal rhythm.
