Worked on the golang/go repository to address year 2038 compatibility for timer_settime on 32-bit Linux systems. Developed a solution in Go that introduces a 64-bit syscall path for timer_settime, defaulting to this modern interface while providing a fallback to the legacy 32-bit syscall if the newer one is unavailable. This approach ensures continued reliability of time operations as Linux evolves, particularly for 32-bit builds. The work involved Linux kernel development and system programming, with careful integration into existing CI workflows and thorough code review. The update improved cross-architecture support and aligned the Go runtime with ongoing Linux syscall updates.
