Moonsnail Mandelbrot, Second Life asked:

Can your skin sense enough light to help with timing issues?

Answer

Ak -   I think the bottom line is that skin cells, although they have intrinsic circadian clocks within them, cannot receive the light and make use of that light.  They need the Suprachiasmatic Nucleus (SCN), the master clock in the brain to actually be able to talk to those cells and resynchronise them.
