Developed high-precision timestamping features for SBNSoftware’s sbndcode and sbnobj repositories, focusing on enhancing data fidelity and event alignment in C++. Introduced picosecond-level support by updating the SPECTDCDecoder module and extending the DAQTimestamp structure with an additional field for picoseconds. Ensured backward compatibility through careful API design, including the addition of multiple constructors to accommodate legacy code paths. The work involved data decoding, data structures, and software engineering practices to integrate seamlessly with existing pipelines. These enhancements improved the accuracy of event ordering and analytics, supporting clearer traceability and reducing ambiguity in downstream physics data analysis workflows.

Feb 1, 2025February 2025 performance summary: Delivered high-precision timestamping enhancements across SBNSoftware sbndcode and sbnobj, enabling picosecond-level timestamps and preserving backward compatibility. Implementations include: 1) SPECTDCDecoder: picosecond timestamping added to FragToDAQTimestamp with TDCTimestampFragment; commit b311e31ae479830ccdb4b55034e9c3c60481b515. 2) SBNObj: DAQTimestamp now includes fTimestampPs for picoseconds, with two constructors for backward compatibility; commit 906edf7b82a77202108e307a080dea812a749ed0. These changes jointly improve data fidelity, event alignment, and integration with existing pipelines, yielding clearer analytics and stronger traceability. Technologies demonstrated: C++ timestamping/DAQ structures, API design for backward compatibility, and careful refactoring to avoid breaking changes.
