title: jq command to convert epoch time
body: <p>I run the following AWS command using the <code>jq</code>, but it returns the time in epoch.</p>
  <pre><code># aws ecs describe-tasks \
      --tasks arn:aws:ecs:eu-west-1:87147902d5269:task/ABC/1a9a276e0a0443d3d37ff954cfa6b1f36bc66 \
      --cluster arn:aws:ecs:eu-west-1:87147902d5269:cluster/CDE \
      | jq -r '.tasks[]|.taskArn,.createdAt,.taskDefinitionArn'
  </code></pre>
  <pre><code>arn:aws:ecs:eu-west-1:871479025269:task/ABC/1a9a276e0a044d3d337ff954cfa6b1f36bc66
  1595602422.013
  arn:aws:ecs:eu-west-1:87147922025269:task-definition/new:1
  </code></pre>
  <p>How can I convert the epoch time into a date within the same command?</p>
