According to Einstein, Time can be affected by gravity and is actually another dimension of the physical universe.

Time cannot be one dimensional. It would assume it is not moving, or your perspective of the object being observed is not changing; it's a relative thing. Time is actually a measurement, or difference, from some origin. Using your example, tomorrow is a change in the variable T on a graph. The value of the change is 1 day. Not sure what the other axis is (I think it's space, which gives it 4 dimensions) but one variable is moving, thus you have at least a line, and a multi-dimensional equation. In other words try to graph a change in time using just one dot. It can't be done.
