Analysis of Time

Is time being determined by the watches?
This is another wonder of this universe!
In the field of theory it is a physical quantity,
Which is measurable-
But I say, that's relative.
In the evolution of each planet, human is incapable of measuring it.

The shortest time taken - euctoseconds -
And then zeptoseconds, and so on
The largest exosecond, or cosmological decade,
However, can timing be determined overall?

This planet is here from the birth of the universe to the eternity
(though on one knows for sure).
Some moments, some periods, some days, some years,
Some eras, some centuries, some millennia-
It all depends on each other;

Time!
The bridge is limitless,
Don't depend on anything-
Flows from time immemorial,
Clear, smooth, infallible.
