If time is defined in a way that can't be measured then it only exists in your imagination. While it's possible to say that clocks do not measure time the same can be said about rulers and space. Do you have a problem with those as well?

I always understood that clocks measure time because they define it. Isn't that how any measurement works, by choosing an arbitrary standard and making comparisons to it? Of course our standard for time is not perfect as it depends on relative motion, but as long as we understand how motion affects our measurement of time I see nothing wrong with it. Until we come up with a better way of measuring it, the current definition of time is as good as any other, possibly even better than most. What can we achieve by doing away with it when we have nothing better to offer other than a gut feeling which is most likely mistaken?
