TIME EXIST OBJECTIVELY
Existence is the state of things to be real or ideal. The ideas have subjective existence and they are classified in: logical, emotional and imaginary. Logical ideas are mathematical entities: numbers, figures and measurements. Real objects are material and therefore are objective.
I like your reasoning, but disagree with the concept of ideas (imaginings) consisting of numbers, figures and measurements experiencing time. I can imagine a dragon flying, spewing fire from its mouth. But a dragon is a non-existent animal and as such does does not objectively exist or requires time. The imaginings (duration of thoughts) of the dragon are objectively real and do require time. However the imaginary object itself has no physical properties and does not require its own time for existence in reality.
In some philosophies imaginary objects may become real as Tulpas.
Tulpa also translated as "magical emanation", "conjured thing" and "phantom" is a concept in mysticism of a being or object which is created through sheer spiritual or mental discipline alone. It is defined in Indian Buddhist texts as any unreal, illusory or mind created apparition.
Chidambaram Ramesh, an Indian author and researcher, has mentioned in his book "Thought Forms and Hallucinations" that the creation of thought forms and other mental entities like Tulpa etc., is the result of holographic mind processing

Becoming-duration duality is real and its measurement, time, is a logical idea. Measurements do not depend on the view of the subject, therefore, in a sense they are objective.
IMO, that is only partly correct, an imaginary dragon (Tulpa) cannot be measured by any measurement. It does not exist in reality. God, Devil, Angels, spirits are all Tulpas. This is why no time frame can be assigned to them, they have no measurable qualities in and of themselves.
Now, the perception of time, what each individual perceives, is completely subjective, a false time.
I agree somehwat, but instead of "false time" I would prefer to use "relative time" depending on the individual's viewpoint.
Anyway, whether in reality or in the mind of the subject time exists objectively.
With a stipulation that whereas the individual's mind exists in the present, the time (of a thing) it perceives is always from the (fixed) past, IOW, reality (as we preceive it) has already happened (fixed in time) and is part of observable reality, before it can measured accurately.
- Objective 1: It exists in the reality (table, light, motion, etc.)
True, but measurable only from the past (elapsed time) and only by it's observable physical properties .
- Objective 2: It exists in the subject, but it is an universal truth (numbers, figures and measurements).
IMO, if something has measurable properties it may be said time can be associated with those properties.
But Mathematics has no time frame of itself. Only measurement (using numbers and equations) yields a functional time frame. The number 2 has no associated time frame, E = Mc^2 has no associated time frame. These constants are timelessly true.
The one constant which may by associated with a specific time frame is "c", but that is because this constant has a measurable property, because it is associated with a physical particle.
However when we dig deeper, we reach first "uncertainty" where space and time are not measurable simulataneously, even as a "coordinate" for the particle may be established.
Deeper than that we reach Potential and enter the world of metaphysics (constants) and time
loses any meaning alrogether. Does time exist as a property nothing?
If the universe ceased to exist there would be no spacetime, IOW, no space (geometry or change), no time.
Time does not exist for unreality. Such a condition should be considered "timeless", IMO.
