Who else sleeps outside of their actual designated time zone?

I'm pretty sure I'm non-24 and that I have some weird wiring in my brain that forces me to be more nocturnal. Sunlight makes me extremely sleepy and even if I stayed up for 24 hours by the time night falls I feel more energetic again. I doubt it's SAD syndrome--I live in Florida and the difference between daylight and night hours is 4 hours between the solstices. But it's almost 9AM for EST folks, and it's more like I'm on Sydney time, and it's 11PM and I need to sleep now... I think I lack a circadian rhythm entirely because there's absolutely no set amount of time I stay awake and sleep for, and no long term schedule helps (the entirety of high school proved that it's not just a matter of bad habit).

I mean, saying goodnight even if it's daytime is accurate for SOME part of the world...
