There's also the allusion in Job 7:2.  Your discussion supports the
point of my original postion.  Although we moderns think of an hour
as a constant amount of time, the hour was merely a fraction of the
day.  As the length of the day varied (as it does even now, with an
average of 24 modern hours), so too did the length of the hour.  It
is the length of the day that is primary and the length of the hour
is derivative.  A definition of a primary concept in terms of its
derivative attributes is ultimately a circular definition, because
the derivative attributes only have a meaning with respect to the
primary concept.  E.g. the circularity in: What is a day?  Twenty-four
hours.  What is an hour?  One twenty-fourth of day.  Therefore, it
is only proper to use a non-circular definition: the period from
one morning/evening/noon to the next.  This definition is superior
because it is non-circular and the one that the writer actually
seems to employ in Genesis 1.

It is either tautological or illegitimate.  It is tautological, if an
hour is defined as a fraction of a day (as the ancients did), because
every day can be divided into 24 parts, but this does not tell us how
long the day or the hour is.  It is illegitimate if one assumes that
hours are constant and can be used to measure days (as they now in
modern times with our clock-making technology) to imply that the
Genesis 1 days are precisely measured to the same length.
