Easily defeated (this has to be done by wall clock time, so changing the 
timezone will be enough).  This really has to be done server side, and 
will generally require proof of age more than time constraints. 
Children have computers in their rooms these days, so the watershed 
doesn't really work.

I assume you mean lacking in illumination, rather than in the more 
abstract sense (e.g. "the theme of the latest Harry Potter film is much 
darker than that of the first").

You are trying to second guess how the user is actually viewing the 
site, and, in any case, if they are sensible, they will have turned down 
the display back-light intensity, so the only real effect will be to 
have reduced the dynamic range of the display, as the darkest levels 
will have to collapse into black.  Reflective displays will actually 
require the contrast enhancing.

Did you not research it?
