Actually, you may find this more popular than you might think. This time of year (winter), the monitor screen would change at around 5:00 PM. If you tend to stay up to 11:00 PM, That mean you're looking at a screen with really wrong colors for six hours. That's really way too long. As far as complicating the user interface, I would think of it as a simplification of what you are doing now. Really just a way to specify fixed times to change the screen.
