When were clocks used for the first time in science?

When were the first mechanized timekeepers used in science?

The beginning of the month in the Babylonian calendar was determined by the direct observation by priests of the young crescent moon at sunset after the astronomical New Moon. This custom is remembered in Judaism and Islâm with the principle that the new calendar day begins at sunset.

When were the first mechanized timekeepers used in science? Was Galileo the first one? Did this use further science a lot?

Time has been mechanized already by sundials. These nails and chains that are banged in and put around time have been increasingly refined to accumulate in the advent of the atomic clock. So-called Natural units were even invented. Without mechanized time the world would have looked very different. Maybe we have some kind of marshmallow minds. Maybe we could better wear aikhornnuts on our wrists as Krznaric puts it.

When were the first mechanized timekeepers used in science? Was Galileo the first one? Did this use further science a lot? So newer means and more precise keepers could be constructed?

Now that I think of it, what about the earth, the moon, and the sun itself viewed as one giant timepiece?

Nice idea. It always gives you the right time when we look at it from far away. Maybe we should gauge all atomic hours wrt to that giant clock.

I have heard about waterclocks in ancient Greece.

Not the first, obviously, but still interesting...

The history of Immanuel - The Königsberg Clock - Kant’s life is difficult to describe. For he neither had a life nor a history. He lived a mechanically ordered, almost abstract, bachelor life in a quiet out-of-the-way lane in Königsberg, an old city at the northeast border of Germany. I do not believe that the large clock of the Cathedral there completed its task with less passion and less regularity than its fellow citizen Immanuel Kant. Getting up, drinking coffee, writing, giving lectures, eating, taking a walk, everything had its set time, and the neighbors knew precisely that the time was 3:30 P.M. when Kant stepped outside his door with his gray coat and the Spanish stick in his hand.

The instrument is believed to have been designed and constructed by Greek scientists and has been variously dated to about 87 BC, or between 150 and 100 BC, or to 205 BC, or to within a generation before the shipwreck, which has been dated to approximately 70–60 BC.
