This isn’t super common where I am (although you can do it). I had a coworker who practiced something like this so they could go to the gym in the afternoon when it would be less crowded. Or for the soccer example, not much of a choice if you want to watch live European sports.

Also at least in Seattle it seems like every doctor’s office keeps bankers hours (M-F 9-5) so you would have to disrupt your own workday to go to an appointment, though in practice I haven’t known people to bother putting in extra work if their projects are reasonably getting done on time.
