A lot of software engineers grew up working late and it's hard to break that habit or it just doesn't feel natural. I have no problems with waking up at 6:30 to make it into the office but if I had the choice I would pick 11 because it fits with my natural preferred schedule I've spent most of my life living.

Unless you have a legitimate medical issue it only takes a few weeks to reset your schedule.
