BTW Time is a dimension. It does not dilate etc. However, velocity changes one's perspective. See Lorenz Transformation equations.

Einstein was the one who put time into the equations, he tied it to the count of a clock by multiplying a relative count by the square root of a negative one and the speed of light. We use the photon as our yardstick and the count of this dilating wave is how we measure the dimension of time.

A dimension is a mathematical object, not a physical one, so this statement requires some further clarification. Specifically a dimension is a co-ordinate system used to define the location and/or momentum of physical entities. In spacetime physics time is represented as a Cartesian dimension orthogonal to three dimensions of space and for this reason Einstein described spacetime as a mathematical entity and NOT a physical one. Representing time in this way was simply a mathematical convenience which can make no statement about the nature of the universe because Cartesian dimensions are bi-directional mathematical objects whereas time is patently NOT. The arrow of time is resolutely uni-directional whereas most of the equations of physics are time invariant. Significantly not all of them are.

Time is how we account for all the motion that we do not see, it is how we count existence of a single point in space time. +++-, ---+ the focal point for a coordinate system is always centered, in space-time with a clock an anchor point of mass.

Einstein's General Relativity shows that it is utterly impossible to synchronise two clocks, no matter whereabouts in the universe they are placed relative to each other. This has been empirically verified countless times and must apply all the way down to the Planck scale, which means that GR is incompatible with SR, which assumes the opposite.

Does not GPS show us that there is in fact one instant that we all share as the present, even if we can not see it?

Actually, Einstein showed that gravity is curved spacetime, not just a function of time. Are you actually claiming that Einstein did not unify space and time into spacetime?

After all the proof that a clock lower in a gravity well will tick at a slower rate that one higher you would think a longer second would account for the curve the closer to the center of mass.
