People may take the shit you say as real.

The term 'Time' is actually derived from the process of counting repeated events, which occur at the same frequenecy. This process of counting starts somewhere and ends at the event in question. Now 'time per se' requires a starting point and an endpoint, while clocks don't show the starting point. This start is somehow set, like e.g. by the birth of Christ, and subsequently taken for granted and not explicitly mentioned. A perfect and perfectly set clock would show the usual result of the counting process, but only the endpoint, hence the clock does not actually measure time. What clocks do, that is mainaining an internal representation of this process, by which time is usually measured and count the occurences of some sort of events. Then this is devided by some constants and presented in user friendly form. So: clocks do not measure or show time, because they can only show one side of an interval. The other side is subject to arbitrary decisions. ... TH
