Subject/title: Technical Paper on Global Coordination Requirements for 2038-class rollover events (including but not limited to 2036, 2038, 2106)
Status: Under study 
Approval process: Agreement
Type of work item: Technical paper
Version: New
Equivalent number: -

Supporting members: FIRST, Broadcom Europe Ltd.
Summary: The paper will document known and emerging failure patterns within ICT systems—particularly those dependent on legacy 32-bit time representations—and examine systemic challenges in discovery, inventory, testing, and cross-sector coordination. The work highlights the structural limitations of remote detection and simulation-based testing for rollover-class failures. Historical analogues such as ESA's 1996 Ariane 5 incident illustrate why in-situ validation and multi-stakeholder coordination are essential. It further recognizes that effective coordination requires common terminology, conceptual models, and shared prioritization approaches across standards bodies. The resulting Technical Paper will not impose normative requirements. Rather, it will provide globally aligned framing of the problem, identify areas requiring future study or inter-SDO collaboration, and support Member States and operators in preparing for potential correlated failure pathways before rollover thresholds are reached.
