One more about the stone form...

I noticed that often times there are shots of the rising sun, but the Gargoyles remain flesh until the light rays actually hit their body. This seems to imply that it is the actual physical impact of the sun rays on their bodies that turn them to stone. But by that token, a gargoyle hiding inside a dark room with no windows would remain flesh during the day. So instead, do they have some sort of biological clock, in tune with the rotation of the earth? But that seems even too complicated for a gargoyle. I'd like to hear anything you had thought out concerning the specifics of this idea.
