They have no sense of time of day. They could be falling asleep at 10PM or 10AM. But once you turn off the lights, they will think that it is night time. Speaking metaphorically of course.
I don't know about that but this clock you talk of is preset (instincts) and any amount of cursory changes might not have an effect on it.
I think snakes do more then just sense daylight hours and sun angle degrees to tell them it's brumation time. I have no proof of this but believe there is far more to it then that.
Just my opinion.
