介绍一个nodejs非常实用的日期时间插件：Date-Utils

在nodejs中最常用的就是日期时间的格式化，但是nodejs本身实现不是很好，在网上找一番之后发现Date-Utils是最好用的，方便，简单易用。

简单效果实例

废话不多说，先看下效果：
格式化一个最常用的日期时间格式就是：yyyy-MM-dd HH:mm:ss<==>2015-09-22 09:40:49
其实输出这种格式的代码非常简单：

require('date-utils');
var dt = new Date();
console.log(dt.toFormat("YYYY-MM-DD HH24:MI:SS"));

安装

Using within a Browser

<script type="text/javascript" src="date-utils.min.js"></script>

Using with Node.js

$ npm install -g date-utils
require('date-utils');

Note: This did not work in the REPL before Node.js 0.6 due to how Node.js handles context in the REPL.
