February 2026: Stabilized date-time handling in apache/arrow-rs by delivering a Chrono compatibility fix and reinforcing test coverage, enabling reliable builds with Chrono >= 0.4.40. Implemented a targeted fix in get_date_time_part_extract_fn() to route DatePart::Quarter to Datelike::quarter(), preventing build failures caused by Chrono's quarter() clash with Datelike. Added tests to exercise the extraction path and confirm correct behavior without user-facing changes. Ran benchmarks and maintained performance parity. The change reduces friction for downstream users updating Chrono in their Cargo.lock, improving overall reliability and adoption potential for time-related functionality across Rust projects. Demonstrated proficiency in Rust, cargo-based workflows, cross-crate compatibility, testing, and performance validation.
