/**
 * <p>Modifies the specified event window.</p>
 *          <p>You can define either a set of time ranges or a cron expression when modifying the event
 *          window, but not both.</p>
 *          <p>To modify the targets associated with the event window, use the <a>AssociateInstanceEventWindow</a> and <a>DisassociateInstanceEventWindow</a> API.</p>
 *          <p>If Amazon Web Services has already scheduled an event, modifying an event window won't change the time
 *          of the scheduled event.</p>
 *          <p>For more information, see <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/event-windows.html">Define event windows for scheduled
 *             events</a> in the <i>Amazon EC2 User Guide</i>.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { EC2Client, ModifyInstanceEventWindowCommand } from "@aws-sdk/client-ec2"; // ES Modules import
 * // const { EC2Client, ModifyInstanceEventWindowCommand } = require("@aws-sdk/client-ec2"); // CommonJS import
 * const client = new EC2Client(config);
 * const command = new ModifyInstanceEventWindowCommand(input);
 * const response = await client.send(command);
 * ```
 *
 * @see {@link ModifyInstanceEventWindowCommandInput} for command's `input` shape.
 * @see {@link ModifyInstanceEventWindowCommandOutput} for command's `response` shape.
 * @see {@link EC2ClientResolvedConfig | config} for command's `input` shape.
