What is wrong in this statement?

Question

Any number is a frequency (you can adjust your unit of time according to the number you want the frequency to be) when it is not changing. But no number is a frequency when it is changing, your stop watch would show unit of time and duration independent of rate of change.

Answer 1

Its a biut incoherent, but if its saying what I think it is trying to say then the existence of FM radio proves it wrong.

Answer 2

The statement could be made for anything that is not constant.  For example, if a car has a constant velocity, it can be represented by a single number, e.g. 50 m/s.  But if the car is accelerating from 0 to 50 in 20 sec.  What is the velocity?  There is no single number that can express it.  The same is true for the frequency statement.  However, it is possible to express the frequency at a given moment of time, just as it would be possible to express the velocity of the accelerating car at a given moment.

Answer 3

Time itself is a steady flow

It does not accelerate or decelerate (a basic assumption)

But processes can go faster or slower: e.g. if a pendulum's length shrinks with temperature changes, the frequency is a changing number
