Regulate screen brightness according to the time

One of the problems posed by back-lit screens is that they can affect us by being excessively bright. Ideal levels of brightness are those which adapt themselves to ambient lighting and although we can adjust this manually, it can also be controlled automatically with applications like Twilight.
