A sane date/time library for Rust.
This library primarily ports the API of the excellent java.time library.
It is also leap-second aware.
Like the Java API, this crate implements its own type named Instant.
However, unlike the Java version, this instant is explicitly not a UTC instant, but instead is a TAI instant.
Like the Java API, this crate implements its own type named Duration.
Unlike std::time::Duration, ephemeris::Duration can be negative.
