Jiff (via) Andrew Gallant (aka BurntSushi) implemented regex for Rust and built the fabulous ripgrep, so it's worth paying attention to their new projects.
Jiff is a brand new datetime library for Rust which focuses on "providing high level datetime primitives that are difficult to misuse and have reasonable performance". The API design is heavily inspired by the Temporal proposal for JavaScript.
The core type provided by Jiff is Zoned, best imagine as a 96-bit integer nanosecond time since the Unix each combined with a geographic region timezone and a civil/local calendar date and clock time.
The documentation is comprehensive and a fascinating read if you're interested in API design and timezones.
