See https://github.com/tomaka/clock_ticks/pull/4 clock_ticks is based on this library, so I suspect the same issue applies here. https://github.com/rust-lang/time/blob/a9b589595eaffd9f5b6a4b53bc89a32246204ac2/src/lib.rs#L251 ``` Rust return (ticks as u64 * 1000000000) / (imp::frequency() as u64); ```
