title: How to trigger Jenkins downstream build job with a delay?
body: <p>From the <code>test-upstream</code> Pipeline job, I call <code>test-downstream</code> as below:</p>
  <pre><code>build job: &quot;test-downstream&quot;, parameters: [[$class: 'LabelParameterValue', name: 'computer', label: env.NODE_NAME]]
  </code></pre>
  <p>it works, but is there a way to delay the start, or schedule it to run 30 minutes later?</p>
  <p>Looking for something like:</p>
  <pre><code>build job: &quot;test-downstream&quot;, delayStart: 30m, parameters: [[$class: 'LabelParameterValue', name: 'computer', label: env.NODE_NAME]]
  </code></pre>
