   Project mention: Jiff: A brand new Datetime library for Rust, from the builder of ripgrep | news.ycombinator.com | 2024-07-21

   In Java they had the same problem. The Java standard library implementation wasn't great, Jodatime came along to address those issues. Java 8 then introduced a new DateTime API that was heavily influenced by Jodatime with the benefit that as it is in the standard library, it can be more heavily adopted by library-writers.
