I meant, that time is not based on clocks, because clocks are man made and time is not. The 'real thing' is an entirely different thing than the model describing it. The one who makes models is called 'observer' and that's the one who measures and uses devices like clocks. But that has nothing to do with how time actually functions as a natural phenomenon. This is obviously the case, because clocks had in former times tiny cogwheels inside. And it makes no sense whatsoever to assume, that there are numerous cogwheels in nature. How time functions is actually an interesting question. But that has nothing to do with how clocks operate. TH
