Your answer gets support from Wikipedia,but not by physics.'Time' as far as i understand,has hardly to do anything
that is conceived out of definitions of existing three dimensions.I find no conceptual or mathematical relevance between the two.'Time' is a factor that relegates to a process of aging of a chemical reaction or a like happening.
I suppose,as no proper categorisation has so far been found out to pin down the 'Time' into,hence it is heaped into head of chapter of dimensions, just for literary satisfactions.
A state of things to be categorized as 4th Dimension,must bear a direct relevance of it,to a three D surface,across a perpendicular upon it,enable it to encompass a space out of reach of space cover able by mother surface,a set of things not remaining inconsistent to each other,so that a mathematical resonance and interrelationship could be found out,to establish
a perfect relation in between the four.
So far as it relates to theories of mind,i would like to submit that
mind is thoroughly incapable of imagining any thing that already not remained the subject of your knowledge.?
