<p>The <code><strong>setYear()</strong></code> method sets the year for a specified date according to local time. Because <code>setYear</code> does not set full years ("year 2000 problem"), it is no longer used and has been replaced by the <a href="Reference/Global_Objects/Date/setFullYear" title="setFullYear() 方法根据本地时间为一个日期对象设置年份。"><code>setFullYear</code></a> method.</p>
