Yeah, sorry, that was a bit of a knee-jerk response from me. I took TillE's comment to be more a statement of the general (IMO unfounded) mistrust of floating point, and my comment was intended to take it in that light. Once you have values in the domain you're interested in, floating point more than suffices for precision, and generally handles rounding better than the equivalently-sized fixed point variable. I do agree that a general timestamp needs to be domain-agnostic, and I'm certainly not saying Rust should use it, not least because Rust aims to preserve the semantics of underlying APIs.
