January 2025: Strengthened reliability of the facebook/time module by addressing a critical issue in sync packet length calculation when Alternate Port TLVs are present. The fix ensures proper packet formation across variable TLV sizes, improving communication reliability and reducing risk of malformed packets in production. No new features shipped this month; the focus was on robustness and maintainability, with clear traceability to commits and tests.

December 2024: Focused PTP port handling enhancements in facebook/time delivered a robust, scalable port management workflow for PTP servers. Implemented dynamic port assignment, port-aware ptping handling to ensure announce packets reach the correct destination, and a revised portID generation starting at 11 to minimize conflicts with other tools. This work reduces misrouted time announcements and improves multi-tenant reliability. The changes were implemented via incremental commits to refine PtP interoperability while preserving backward compatibility. Overall, these improvements enhance time synchronization reliability in multi-service deployments and simplify future instrumentations.

October 2024: Delivered targeted fixes and feature enhancements in facebook/time to improve cross-architecture reliability and NTP data handling. Core achievements include stabilizing PHC tests on s390x, preventing duplicate SPTP steps by resetting FirstUpdate on servo lock, and introducing RPY_NTP_DATA2 support in the chrony NTP client. The work reduced clock-related failures, improved observability, and expanded data fidelity for NTP packets.
