How do we actually know what the time is? Is there some “master clock” that all time zones are based on? And if so, what does THAT clock refer to?

EDIT: I believe I have kicked a hornet’s nest. Did not expect this to blow up! But I am still looking for the “ur time”. the basis for it all. Like, maybe the big bang, or something.

There are fundamental physical truths that if you’ve never thought about, time can seem more baffling.
There is a point in the day that the sun is highest. This happens every day and it is always the same amount of time between the high points one day to the next – it makes no difference if it’s summer, winter etc. or if you are in the North Pole or on the equator. always the same. At that point in the day the number of daylight hours that remain is exactly the same as the number that have passed. I.e. it is the exact middle of the day. It follows that at that point plus or minus half the time between high points is exactly half way through the dark period of a day (night). Everything else follows on from these facts.
