When a derivation step silently calls a &ldquo;now&rdquo; primitive, two replays of the same nominal history can diverge in bytes and in downstream decisions. That failure mode is orthogonal to intent: it is an engineering fact about implicit clocks.</p> <p>A parallel issue is representational. Civil calendars and stepped scales—UTC with its leap-second policy—are built for human coordination and Earth rotation, not for &ldquo;same input, same output&rdquo; lineage. The telecommunications and distributed-systems literature documents operational friction from that discontinuity class (<a href="https://www.itu.int/hub/2023/05/synchronization-and-the-impact-of-utc-discontinuities/">ITU, &ldquo;Synchronization and the impact of UTC discontinuities,&rdquo; 2023</a>). Choosing what to treat as canonical time for append-only history is therefore a design decision with testable consequences.</p>
