Let’s see what the mathematics of SR says about this issue.

We have an event taking place in (flat) spacetime that is observed by #1, #2, and #3.  Three sets of the Lorentz transform can be written down comparing how #1 and #2, #1 and #3, and #2 and #3 observe the same event.  Interestingly, all these sets of the transformations can be written down into a single precise equation below.

**  dt₁² – ds₁²/c² = dt₂² – ds₂²/c² = dt₃² – ds₃²/c²

Where

**  dt₁ = Local clock tick rate at #1
**  dt₂ = Local clock tick rate at #2
**  dt₃ = Local clock tick rate at #3
**  ds₁² = dx₁² + dy₁² + dz₁² = observed length by #1
**  ds₂² = dx₂² + dy₂² + dz₂² = observed length by #2
**  ds₃² = dx₃² + dy₃² + dz₃² = observed length by #3

It should not be too difficult to figure out the following from the above.

**  dt₁² (1–β₁²) = dt₂² (1–β₂²) = dt₃² (1–β₃²)

Where

**  β₁² = (ds₁²/dt₁²)/c², speed of the event as observed by #1
**  β₂² = (ds₂²/dt₂²)/c², speed of the event as observed by #2
**  β₃² = (ds₃²/dt₃²)/c², speed of the event as observed by #3

Furthermore, it should not be too difficult to extrapolate the above into the following. 

**  dτ² = dt₁² (1–β₁²) = dt₂² (1–β₂²) = dt₃² (1–β₃²)

Where

**  dτ = Local clock tick rate at the event being observed by #1, #2, and #3

Let’s say the absolute frame of reference does exist.  In this case, the following can easily be constructed.

**  dτ² = dt₀² (1–β₀²) = dt₁² (1–β₁²) = dt₂² (1–β₂²) = dt₃² (1–β₃²)

Where

**  dt₀ = Local clock tick rate of the absolute frame of reference
**  √(β₀²) c = Absolute speed of the event

Notice there is no such thing as the proper time.  The closest what the religion of SR and GR refers to the proper time is the local clock tick rate of the event being observed by all observers.

For more details, please refer to the following treatise.

Moron, a proper second on any clock is a clock second at its location. A proper second on any clock represents a specific amount of absolute time and this amount of absolute time is related via the LT. For example: a proper second on my clock is worth 1/gamma second of proper time on your clock. IOW you clock is accumulating proper clock second at a slower rate compare to my clock by a factor of 1/gamma.

You need to get rid of this “SEE” business. No observer sees the clock rate of any moving clock. He predicts the rate of a moving clock.by the SR
Also you need to get rid of the faulty reciprocal clock rates as assumed by SR. In real life clocks in relative motion accumulate clock seconds at different rates.

You are a moron, there is no hope for you.

Your assertion is not a valid argument. "Proper second" is meaningless
gobbledygook, since here is only one kind of second.

>and this amount of absolute time is related via the LT.

Your assertion is not a valid argument. Plus there is no such thing as
absolute time in the Lorentz Transform.

>proper time on your clock.

Once again, you aren't using the term 'proper time' correctly. "Proper
second" is gobbledygook. There is only one kind of second.

They can, depending on the type of clock (doesn't have to be something
that resembles Big Ben) and the type of communication.

But regardless, replace "see" with "observe", "measure" etc. if "see" 
bothers you that much.

> He predicts the rate of a moving clock.by the SR

Prediction is meaningless. I predict nice men in clean white suits with a
giant butterfly net will come tomorrow to take you back to the asylum.

Not "assumed", this is a measured result.

You shouldn't address yourself in the second person like that.

Poor fanatic idiot is enchanting the reality.
As expected from a poor fanatic idiot.

Mike, poor idiot. Your delusions of what is observed
didn't match real observations even in Galileo's time.
Now they are not even worthy laughing at.

Moron, a proper second is a clock second at the rest frame of the clock. A proper second of the observer’s clock represents a specific amount of absolute time. On buses the LT to transform this amount of absolute time to a moving clock and the result is: 1/gamma second on a moving clock.

Moron, production is the whole purpose of the LT.
