Standard Second and Starting with the End in Mind

It is fine on paper to insist on a standard second, s = 1 sec, but in practice a standard second is difficult to define.  However if time is the flow of space and space has mass, m.  We might consider:

$t={ C }_{ o }.\cfrac { dm }{ dt }$ a flow of space through an unit Area A and over time, a volume of space, mass m and ${ C }_{ o }$ is a constant of proportionality independent of time.

Solving this

$\int { tdt } ={ C }_{ o }\int { dm }$

$\frac { 1 }{ 2 } { t }^{ 2 }={ C }_{ o }m$

and so,

$t=\sqrt { 2{ C }_{ o }m }$ where m is the mass of space.

This allows us to move onto the concept of Gravity.
