In brief: Yes
Natural circadian rhythm is known to be 25 hours.
The "clock" is in the part of the brain which computes our ability to adapt to the mental and physical stresses imposed by environment. We compress the 25 hour to a 24 hour rhythm, thus adapting to our world. The 24 hour rhythm obeys the dark/light cycle and is indeed controlled by the computer in the brain.
