Time is a 4th dimension when talking about spacetime, which assumes three dimensions of space and one dimension of progressing time.
Yeah, that’s basically what I was referring to. Everything I know about dimensions, I learned from Doctor Who, Hitchhiker’s Guide to the Galaxy and Donnie Darko!

FWIW our current understanding of spacetime includes multi-dimensional time, which is why we experience more or less time when we are traveling at high speed or experiencing strong gravitational fields. It’s sort of like moving diagonally across a room, except entirely different.
