{# Clock-corrections intro prose + per-instrument offset/drift table.  The

<p style="font-size:0.82rem;color:var(--gray-5);margin-top:-0.5rem;">
  Positive drift/offset = instrument was <em>slow</em> (behind UTC); correction shifts times later.
  Negative = instrument was <em>fast</em> (ahead of UTC); correction shifts times earlier.
