There are multiple studies that show that the time that you sleep does matter. There is a higher risk of diabetes and obesity for people who sleep during the day and are awake at night. I'm not saying this to be a buzz kill, I really wish it wasn't true. Anecdotally, I used to keep very, very late hours and sleep a lot of the day - and I did this for years. I thought I was fine. Once I established a normal day/night cycle (kids and wife do that to you), I realized that I had been grumpy most of the time and not particularly happy. Soon after establishing a more normal rhythm, I also lost a considerable amount of weight (about 15lbs).

It's less the time, and more how it interacts with the rest of your live. Like the bodies instinct related to light amount and how you allow your body to sleep getting out of sync. Or how day time tends to be more noisy and as such is more likely to disrupt your sleep. Or how meeting people fits less into your sleep cycle. Or how most people are not night active all the time, but switch between periods of night shifts and e.g. not being night active on your free days (because you e.g. can't go to the SPA at 2am). Or how bright lights, even such advertised as daylight lights, often do not replace day light properly. Etc. So, while the time doesn't matter directly in practice having a "off" cycle is much much more likely to affect your life implicitly in negative ways then a more day aligned cycle.

  Yes, obviously it is about the day/night cycle and not about absolute time because people on the other side of the planet are just fine. But while the absolute time may not matter, the time you are awake during the day/night cycle does matter. You can try to tell yourself you can live outside this day/night cycle, but we just didn't evolve that way.
