The real absolute time could be many magnitudes faster than that. Our entire universe could be within some outer "universe" such that the whole of our universe is running at snail pace. This would make sense too when you think about "instantaneous" action at a distance with quantum stuff.
If you don't have that faster time, you can't have a time slowed by energy density because it isn't running slower than the faster time that the model doesn't have.
If you make sure you have removed absolute time from the simulation, the simulation will cease to function correctly. Indeed, it will fail to function altogether. You cannot have coordination of different "times" without one of them governing the other(s).
The masking would never be perfect, so it turns out that it isn't a problem, but let me explain the line I was thinking down. Imagine a glass tank with a light clock in it. Fill the tank with water and the light clock runs slow. Empty the tank and the light clock speeds up again. Now send a signal in and repeat the experiment. The signal slows down, but the frequency won't change, so the light clock (if it has a detector that can measure it and time it against light clock time) will detect it as having a higher frequency - exactly as you say. However, if you have a changing gravity well that engulfs the signal over a long distance from the side, that will slow it down such that the frequency is lowered.
It will not. So long at the path doesn't change, the frequency of the light cannot possibly change in any one frame.

Raise the level of the water in just one second such that the light beam is now in water rather than air....You couldn't actually do that with water as it would reflect the light away on contact when you change the water height, but it could work if done with a changing gravity well instead, and the change in frequency would for a while match the change in the detector's clock (a light clock) such that no change in frequency would be detected by that observer even though there would be a real change in frequency.
Has there been an instant change in the number of waves in the light? No.
Has the light slowed down? Yes.
Has the frequency dropped? Yes, though not for the light entering the tank at the end.
The water won't work for the reasons stated, and gravity can't just be switched on, but it sort of can if you have a pair of massive rods that can be set close by or further away.
Light doesn't come in waves, it comes in photons.
Not sure how you would measure the frequency of a photon while still in there. I think it depends on if gas or gravity was the agent. Expose it to photographic film and see what color it shows. Would film in the gas show different color than film in the gravity field? How big of refraction/dilation would be needed to tell the difference?
If you have a gravity well with changing length contraction on it due to the source(s) making rapid changes in direction of travel, then you effectively have gravity being turned up and down, and the change can be rapid and near-instantaneous along a long length of the path the signal's travelling along (perpendicular to the gravitational source).
[Light] has a wave nature with crests and troughs. A measurement of frequency is (at the lowest level) a measurement of how many crests arrive in a given length of time. The distance between two crests doesn't change as the gravity well changes shape.

Surely light coming from a star at color X is not all in phase, and measurement of the wavelength of it isn't done by counting crests over time. Twice as much green is still green. I suspect they measure the energy of each photon and extrapolate the wavelength from that. That's how eyes do it.
Picture a spherical gravity well. Draw a circle to represent it on paper, and the line will represent a contour of equal gravitational pull. Now take the central object which generates the gravity well and move it at 86.6c across the page, or imagine the page moving at that speed so that you don't have to move the object. The gravity well must contract to half its rest length in the direction of travel, so if the object's moving upwards, you should imagine the page moving down instead and the circle should be contracted into an ellipse with its shortest diameter half the size of its longest diameter (if diameter's the right word to use when dealing with an ellipse).Now, there could be two black holes of equal mass forming our object, and they're orbiting each other, but both of them will always be moving in opposite directions and will have length contraction applying on them in the same direction. A quarter of an orbit further on, the length contraction will be applying perpendicular to the way it was applying before. What you'd actually get would be like an ellipse rotating.
Now, draw a dot somewhere inside the original circle, but outside of the original ellipse. Then rotate the ellipse and visualise the line crossing the dot. Zoom in on the dot and observe how the line that crosses it looks more and more straight. For the dot and the space to either side of it, gravity is effectively being turned up and down just as if someone was controlling it with a slider switch.
If you do this with the dot far enough away from the black holes, the changes in the speed of functionality of the dot's light detector will be masked by the changes in the speed of the laser light, making the frequency appear constant.
If light is a wave,
If light is a wave, each photon must be spread out over a distance with a frequency which manifests itself as a side-to-side movement of the wave. If you try to turn all of that into nothing more than point particles, the frequency is going to be lost, and so will the ability to red or blue shift it.
To detect sound of a specific frequency, you can do it by having something that resonates at a particular frequency so that the crests and troughs (which are the same thing if we aren't dealing with surface waves) cause it to move to and fro in response to the wave passing.
In the same way, two photons can be less easy to detect than one if they happen to cancel each other out at the detector - all the energy is still present, but it can be made incapable of interacting usefully with the detector in such a case...Send ten photons in at once and there's very little chance of them all being cancelled out entirely, but most of the signal will still be missed due to it being cancelled out.
Orbiting black holes are a lousy example since each one deforms the ring of equal potential of the other, so it isn't a circle anymore.
OK, I get that, but what does the dot represent?
I think you're picturing two black holes, but there is no aiming a beam of light at the dot, which is not a fixed location. You aim it near one of the singularities or not. Nothing is changing a perspective.
Light has a wave-like nature in some ways. I don't think anybody says light is a wave. Waves are not things, they're effects of multiple things.
]Light isn't point particles either, despite it having particle-like nature at times. You seem to be attributing classical properties to a very non-classic entity.
Ears (a 0-D matrix) resonate at thousands of frequencies, which do a mechanical Fourier transform on the waves and send that result to the signal processor.
I agree sort of, but then why does focused light from a random source (the sun say, which hardly puts out synced laser light) not just cancel itself to almost nothing? No, it fries the ant. Most of the signal does not in fact go missing. Where would the energy go if it canceled? Seems to violate conservation.
