Worked on the rerun-io/rerun repository to standardize date and time handling across multiple modules, focusing on improving consistency and maintainability. Migrated existing time and chrono dependencies to the jiff library, consolidating date-time logic for build processes, analytics events, and notification ages. This approach reduced dependency complexity and established a single source of truth for timestamp calculations, which improved reliability in analytics data and logs. The work was implemented in Rust, leveraging skills in dependency management and date-time handling. These changes streamlined release workflows and simplified future enhancements related to time-based features, contributing to more predictable and stable production deployments.
