They are! I think...

Time is the same as space. It's the same "substance", just distorted in two opposite ways.

You just stated a way in which they are different. Thus, they're not exactly the same. If they are distorted in opposite ways, then, well, that's a difference.

If they were exactly the same, then there would no significance to Ra's choice of using one or the other. But Ra used one in certain contexts, and the other in different contexts.
