Do you think there is an actual connection between the time of the day
and how well your digestive system may work then?  For instance, do you
think that eating after 8pm (or more generally: in the evening) does make
the digestion less efficient? Again, purely because of the time of the
day, rather than any of the factors which may influence digestion and
which you mentioned above.

There has to be a reason for GCB suggestions to "flush" things down with
water after you wake up and stop eating as early before 8pm as possible.
