Many years ago, before there were clocks, time was measured by the rotation of the Earth by observing the positions of the sun in the sky, tides and moon phases.
However, we needed a different measure time appliance accurately
In simpler words, the clock is our position on Earth, with respect to where the sun is at all times. Thus, at 12 days, the sun is overhead, at one day is a bit more towards thesea, and thus moves toward it with each passing hour.
4,000 years ago in Egypt, invented the first watch and was, in fact, the Sundial, only that it could not measure the time when it was night and there was no sun.
