> There are phenomena we call "mass", and hence phenomena we call forces, there is notion of distance, succession, rate of change, but there is no phenomena of time apart from some physical process observable by a mind. The famous clocks being accelerated is mere a mental construct.

Well, you list "rate of change" among your phenomena, but deny time as part of the phenomena. But how can rate of change be a "real" phenomena without time also being "real" in the same sense? "Rate of change" is really "rate of change with respect to time", after all.
