The label for 8 am might as well be the TAFNAP era prince logo. The point is everyone goes to work at TAFNAP, businesses are open until TAFNAP + 8. In case you need to run an errand and talk to the guy that repairs HVAC systems. None of these sorts of errands is pleasurable or light-dependent and might as well be done in the misery of the dark that I lend to my employer for my work hours.
I don't know about you, but in the short winter months I'd rather get to work at night, run my lunch errands when the sun is 3/4 up in the sky, and end my work day with a couple of hours of sunlight to spare in the afternoon when my time is my own than burn sunlight driving in a cubicle.
There are some that manage to make use of early morning light to go surf (when the wind is favorable), or do some farm stuff (when the animals are cooperative??). I'd wager that surfers and farmers are a small portion the population and a lot of workers don't have some intrinsic benefit of spending their workday in daylight vs. night.
One detail -
