An interval between occurrences - - -

An invention and tool of humanity - - -

It is definable - - - It is not tangible - - -

You can't see it - - - Nor is it universal - - -

It had no beginning - - -

And it will have no end - - -

Nowhere else in the existence is time the same - - -

We perceive time in our slot only - - -

Based on our journey around the sun - - -

The interval between occurrences is derived from nature's laws . . .
