<h2 id="语法">语法</h2>
<pre><code class="language-javascript"><code><var>dateObj</var>.setUTCSeconds(<var>secondsValue</var>[, <var>msValue</var>])</code></code></pre>
<h3 id="参数">参数</h3>
<dl>
<dt><code>secondsValue</code></dt>
<dd>一个在0到59之间的整数，表示秒数。</dd>
<dt><code>msValue</code></dt>
<dd>可选参数。一个0到999之间的数字，代表毫秒数。</dd>
</dl>
<h3 id="返回值">返回值</h3>
<p>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。</p>
<h2 id="描述">描述</h2>
<p>如果你没有设置msValue参数的值， 那么返回的值来自<a href="Reference/Global_Objects/Date/getUTCMilliseconds" title="getUTCMilliseconds() 方法以世界时为标准，返回一个指定的日期对象的毫秒数。"><code>getUTCMilliseconds()</code></a> 方法。</p>
<p>如果你指定的值超出了范围, <code>setUTCSeconds()</code> 因此会更新<a href="Reference/Date" title="此页面仍未被本地化, 期待您的翻译!"><code>Date</code></a> 对象中date的相关信息 . 举个例子, 如果你设置secondsValue为100, <a href="Reference/Date" title="此页面仍未被本地化, 期待您的翻译!"><code>Date</code></a> 对象中的分钟数会增加1， 并且秒数会变成40.</p>
