title: REST API response standards: Timezone
body: <p>Is there any ISO standard for how we should return a timezone in a REST API?</p>
  
  <p>If I return a <code>TimeZone</code> type from a ASP.NET WebApi 2 action, the framework serialises the response model to look like this:</p>
  
  <pre><code>{
      "Id": "Dateline Standard Time",
      "DisplayName": "(UTC-12:00) International Date Line West",
      "StandardName": "Dateline Standard Time",
      "DaylightName": "Dateline Daylight Time",
      "BaseUtcOffset": "-12:00:00",
      "AdjustmentRules": null,
      "SupportsDaylightSavingTime": false
  }
  </code></pre>
