 * <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>

 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { EC2Client, DescribeSpotFleetRequestHistoryCommand } from "@aws-sdk/client-ec2"; // ES Modules import
 * // const { EC2Client, DescribeSpotFleetRequestHistoryCommand } = require("@aws-sdk/client-ec2"); // CommonJS import
 * const client = new EC2Client(config);
 * const input = { // DescribeSpotFleetRequestHistoryRequest
 *   DryRun: true || false,
 *   EventType: "instanceChange" || "fleetRequestChange" || "error" || "information",
 *   MaxResults: Number("int"),
 *   NextToken: "STRING_VALUE",
 *   SpotFleetRequestId: "STRING_VALUE", // required
 *   StartTime: new Date("TIMESTAMP"), // required
 * };
 * const command = new DescribeSpotFleetRequestHistoryCommand(input);
 * const response = await client.send(command);
 * ```
 *
 * @param DescribeSpotFleetRequestHistoryCommandInput - {@link DescribeSpotFleetRequestHistoryCommandInput}
 * @returns {@link DescribeSpotFleetRequestHistoryCommandOutput}
 * @see {@link DescribeSpotFleetRequestHistoryCommandInput} for command's `input` shape.
 * @see {@link DescribeSpotFleetRequestHistoryCommandOutput} for command's `response` shape.
