Yeah. I think labeling days is definitely good. I'm glad you changed that.
Personally I'd like to trim milliseconds when dealing with minute+ long runs and seconds from hour+ runs too, since it's all there in the ms output and the units output is for human readability. I see the value of retaining full precision too, though, and don't feel strongly about it.
It should be hard to read without units. I know so now it is maybe late, but the current output is not too readable for me. I miss units - 10s, 1m20.5s, 1h 30m 5s
