/**
 * <p>Describes the events for the specified Spot Fleet request during the specified
 *             time.</p>
 *          <p>Spot Fleet events are delayed by up to 30 seconds before they can be described. This
 *             ensures that you can query by the last evaluated time and not miss a recorded event.
 *             Spot Fleet events are available for 48 hours.</p>
 *          <p>For more information, see <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/fleet-monitor.html">Monitor fleet events using Amazon
 *                 EventBridge</a> in the <i>Amazon EC2 User Guide</i>.</p>
