I think $duration is a thing, which is the time it took to run the previous command. It doesn't separate things like time does, but it's still useful for some cases.

In fact, I customized my prompt to pretty print the previous command's duration if it took longer than 3 seconds or something like that.

I use the Spacefish prompt plugin[0], which does that as well, and comes with a whole lot of other goodness!
