## 语法

    dateObj.setUTCSeconds(secondsValue[, msValue])

### 参数

`secondsValue`
  一个在0到59之间的整数，表示秒数。
`msValue`
  可选参数。一个0到999之间的数字，代表毫秒数。

### 返回值

一个毫秒数，表示从国际通用时间1970年00:00:00到设置的时间值之间的时间跨度。

## 描述

如果你没有设置msValue参数的值， 那么返回的值来自`getUTCMilliseconds()` 方法。

如果你指定的值超出了范围, `setUTCSeconds()` 因此会更新`Date` 对象中date的相关信息 . 举个例子, 如果你设置secondsValue为100, `Date` 对象中的分钟数会增加1， 并且秒数会变成40.

## 示例

### 使用 `setUTCSeconds()`

    var theBigDay = new Date();
    theBigDay.setUTCSeconds(20);
