According to Einstein, time is relative. If I move really fast time is passing slower for me. So time and its effects vary, there should be more than 1 dimension for time in the existing model. Or time should be separated from spatial + other dimensions just because its an outcome of gravity (and other factors) that we cant override and change. This is what Einstein quote is claiming I suppose.

What you are saying makes no sense. Why do you need more than one dimension for time coordinates to express time dilation? How is time an outcome of gravity?!?
>> Why do you need more than one dimension for time coordinates to express time dilation
Because in theory, there is no absolute time we can take as reference. 1 year for an object on moon is not 1 year for an object on Jupiter. So time dimension may include other factors that defines itself.
>> How is time an outcome of gravity?!? "General relativity shows that gravity is really not a force, but rather a consequence of the fact that space-time is curved due to the distribution of mass and energy." More on http://www.ram.org/ramblings/science/time_is_relative.html
