Wrong display of ETA during rust instalation

[q2p]

During installation of Rust on Ubuntu 18.04 it was showing the ETA of downloadable components.
And it should've said ETA: 3 min 4 s, but instead it said ETA: 3.0653233491173086 min 3.9194009470385254 s.

It's probably because values aren't casted to an integer type or because they aren't rounded up.

Here is a screenshot of the process (look at the very bottom):

I did install rust with this command: curl https://sh.rustup.rs -sSf | sh

Here is rustc --version --verbose

Thanks for reporting! It is a rustup issue.
It was fixed in rust-lang/rustup#1699, and the patch will be included in rustup 1.18.0.
