Where does time fit into Einstein's theory space and time?

Question

I have been looking at and researching Einstein's theory space and time more and cannot find an explanation for where time fits into his fabric of spacetime. I can see how space fits into it via gravity and such, but how is time represented in this?

Answer 1

Another reason that the 2D picture is confusing, is that it shows a 3D solid distorting a 2D surface. In reality, familiar 3D objects are actually 4D (3 of space and 1 of time) and their mass distorts a 4D fabric woven from space and time.
