How do the answers to these questions aid in answering the one in the OP?

There should be something that prohibit that the set of cause and effect executes in one instant and its manifestation appear as what we know as time.
D

Why?
B

It is clearly stated. Otherwise there would be no time.

Actually it is not clearly stated. We account with time whether or not it exists. Your point is far from clear.

Time as a measure for rate of change of course can be defined. You are correct though on your observation that what we directly experience is changes and not time but I can then argue that there exist a quality in changes which we can experience and differentiate slow process from fast process. Then the question is that why all process are not extremely fast so all set cause and effect execute in one instant.

the subject of time is a fascinating topic.
we know from general relativity that it is married with space, as in space-time. but going further in cosmology, on the face of it, it can be explained by the 2nd law of thermodynamics and the increase in entropy.
like i mentioned before dr. leonard susskind has very illuminating lectures on the arrow of time posted from the santa fe institute and lectures from stanford and caltech. just google it. you can prepare yourself by reading and doing the exercises in his book “the theoretical minimum”. start from there.
there is also a theoretician, a woman - i forgot her name, and she researches why causality is so fundamental. simulations exist that if causality is not enforced, a universe quickly collapses or could not necessarily exist.
but more fundamentally, you can trace all of this to logic.
logic proceeds from premise to conclusion. more precisely, i believe it is tied to the concept of logical implication. a set of premises flows toward a conclusion but it is not always true that you can reverse a process, keep it logical going the other way around. for reality to exist, it has to be logical. it has to be bound by the rules of logic.
mathematics can describe fantastic worlds but it does not mean it can exist in reality.
then again, only imagination is not bound by logic and it can only exist only in your mind. looney tunes anyone?

I see nothing in the definition of time that restricts the speed at which changes occur. Why is that a problem?
B

Why things doesn’t happen with speed of infinity?
D

I don’t know. Why does it matter?
B

It matters because we can know how our universe functions.

Because it is movement through the space ime fabric. Infinite ‘speeds’ are not possible
And even then, what is our temporal reference frame? Our sense of time would consistant, but what level of ‘change’ happens in reference to an obsever outside our reference frame?
B

The question is why time passes with a very specific rate in a reference frame? Why it is not faster than what we experience, so called psychological time.

I’m surprised that you do not see the contradiction in your statement. Our knowledge of time comes from what we experience about it, and, thus by definition,. our knowledge of time is what we experience.
Even General Relativity comes from experiential epistemology. The Michaleson\Morrely experiments showed that the speed of light was a constant, which meant that time itself was relative.
Also, As a physicist, you should be aware of what at nonsensical phrase "time passes with a very specific rate " is.
What is the unit by which the rate of time passage is so specifically measured? 1 sec\sec? The units cancel, leaving us with unity.

I am talking about psychological time not physical time.

Is not psychological time experienced also?
If not, how else does one come to knowledge of psychological time?
To you consider it to be subjectively real or objectively real?
The reason that I ask that that you mentioned that the ‘time’ you were referring could could be measured, that it passed at “a very specific rate”
How would that be done if you are referring to psyc time?
