If you'd like to contribute to the interactive examples project, please clone https://github.com/mdn/interactive-examples and send us a pull request."><code>Date</code></a> 对象的实例引用一个具体的时间点。 调用 <a href="Reference/Global_Objects/Date/toString" title="toString() 方法返回一个字符串，表示该Date对象。"><code>toString</code></a> 方法以美式英语和人类易读的形式，返回日期对象的格式化字符串。在 <a href="/en-US/docs/SpiderMonkey" title="SpiderMonkey">SpiderMonkey</a> 里，该字符串由日期部分（年月日）和其后的时间部分（时分秒和时区）组成。有时会需要获取时间部分的字符串，这可以由 <code>toTimeString</code> 方法完成。</p>
<p>The <code style="font-style: normal;">toTimeString</code> method is especially useful because compliant engines implementing <a href="https://developer.mozilla.org/en-US/docs/ECMAScript" title="ECMAScript">ECMA-262</a> may differ in the string obtained from <code style="font-style: normal;">toString</code> for <code style="font-style: normal;">Date</code> objects, as the format is implementation-dependent; simple string slicing approaches may not produce consistent results across multiple engines.</p>
