Time is based upon the movement of heavenly bodies (things in the sky) and fundamental ratios of Earth dimensions. All of our measurements derive from these movements and ratios of sizes. Our measurements are very Earth centric, but the "agreement" is forced upon us by the natural harmonics and ratios of the physical system that we occupy.

As just one example of how measuring these harmonics gives us time:

The Earth takes a specific amount of time to rotate on its axis. If we look at the shadow of a pillar (obelisk, sundial point, etc.), the amount of time it takes to reach the exact same point on the ground is One Day. The amount of time the sun shines varies from day to day, but it varies in a repeating pattern. It will reach the same amount of "shining time" every 365 days. We call that One Year.

All measurements of time, distance, mass, etc. come from similar measurable cycles.

Going out one more level; the Earth precesses on its axis. The amount of time it takes to go through one cycle of this precession is 25,800 years. The tip of that precession (like the top of a spinning top) will point into a different part of the sky, a different "constellation" as it precesses. Each 2150 years (1/12 of the Great Year) the tip will point into a different specific constellation. That is where we get the different "ages." We are currently at the end of the age of Pisces (the fish) and heading into the Age of Aquarius. What that means is, the tip of the precession was pointing at the constellation Pisces, and will soon be pointing into Aquarius.

Why do we divide the sky into twelfths? Is that arbitrary? No, but I don't remember off the top of my head why. It has to do with the ratio of something. I will have to look it up. But all measurements are based on these harmonics from an Earth centric viewpoint.
