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.
