  <h1>Time Zone Canonicalization proposal</h1>
  <p>This proposal aims to:</p>
  <ul>
    <li>Improve consistency across ECMAScript engines with regard to time zone identifiers, so that programs will behave more similarly across engines</li>
    <li>Make ECMAScript programs more resilient to changes in time zone identifiers, like 2022's change of <code>Europe/Kiev</code> to <code>Europe/Kyiv</code></li>
  </ul>

  <p>This specification consists of two parts:</p>
  <ul>
    <li>Amendments to ECMA-262, stacked on top of the Temporal proposal</li>
    <li>Amendments to ECMA-402, also stacked on top of the Temporal proposal.</li>
  </ul>
