I have nothing against libraries in general. In this case a general purpose library seems overkill, unless other parts of the application process dates heavily.

Writing small utility functions such as this is also a useful exercise for both beginning and accomplished programmers alike and can be a learning experience for the novices amongst us.

<pre><code>function dateFormat (date, fstr, utc) {
 utc = utc ? 'getUTC' : 'get';
 return fstr.replace (/%[YmdHMS]/g, function (m) {
 switch (m) {
 case '%Y': return date[utc + 'FullYear'] (); // no leading zeros required
 case '%m': m = 1 + date[utc + 'Month'] (); break;
 case '%d': m = date[utc + 'Date'] (); break;
 case '%H': m = date[utc + 'Hours'] (); break;
 case '%M': m = date[utc + 'Minutes'] (); break;
 case '%S': m = date[utc + 'Seconds'] (); break;
 default: return m.slice (1); // unknown code, remove %
 }
 // add leading zero if required

 });
}

entityMap|blocks|key|bgkei|text|如果你使用的是Node.js，你肯定会有EcmaScript+5，所以Date有一个|type|unstyled|depth|inlineStyleRanges|entityRanges|data|d5nds|方法。您正在请求对ISO8601进行细微的修改：|5b1j8|new+Date().toISOString()

If you're using Node.js, you're sure to have EcmaScript 5, and so Date has a <code>toISOString</code> method. You're asking for a slight modification of ISO8601:

<pre><code>new Date().toISOString()
&gt; '2012-11-04T14:51:06.157Z'
</code></pre>

So just cut a few things out, and you're set:

<pre><code>new Date().toISOString().
 replace(/T/, ' '). // replace T with a space
 replace(/\..+/, '') // delete the dot and everything after
&gt; '2012-11-04 14:55:45'
</code></pre>

Or, in one line: <code>new Date().toISOString().replace(/T/, ' ').replace(/\..+/, '')</code>

ISO8601 is necessarily UTC (also indicated by the trailing Z on the first result), so you get UTC by default (always a good thing).

entityMap|blocks|key|9vjbd|text|使用Date对象中提供的方法，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|d02m7|var+ts_hms+=+new+Date();

Use the method provided in the Date object as follows:

<pre><code>var ts_hms = new Date();

console.log(
 ts_hms.getFullYear() + '-' + 
 ("0" + (ts_hms.getMonth() + 1)).slice(-2) + '-' + 
 ("0" + (ts_hms.getDate())).slice(-2) + ' ' +
 ("0" + ts_hms.getHours()).slice(-2) + ':' +
 ("0" + ts_hms.getMinutes()).slice(-2) + ':' +
 ("0" + ts_hms.getSeconds()).slice(-2));

<a href="http://www.mattkruse.com/javascript/date/date.js" rel="nofollow">http://www.mattkruse.com/javascript/date/date.js</a>

and used it. See <a href="https://github.com/adgang/atom-time/blob/master/lib/dateformat.js" rel="nofollow">https://github.com/adgang/atom-time/blob/master/lib/dateformat.js</a>

The documentation is pretty clear.

Easily readable and customisable way to get a timestamp in your desired format, without use of any library:

 pad(d.getMonth()+1)+dash+
 pad(d.getDate())+" "+
 pad(d.getHours())+colon+
 pad(d.getMinutes())+colon+

After a few gray hairs I figured out that is was actually pretty simple.

<pre><code>var date = new Date();
var year = date.getUTCFullYear();
var month = date.getUTCMonth();
var day = date.getUTCDate();
var hours = date.getUTCHours();
var min = date.getUTCMinutes();
var sec = date.getUTCSeconds();

var ampm = hours &gt;= 12 ? 'pm' : 'am';
hours = ((hours + 11) % 12 + 1);//for 12 hour format

var str = month + "/" + day + "/" + year + " " + hours + ":" + min + ":" + sec + " " + ampm;
var now_utc = Date.UTC(str);

Add the UTC offset to the local time then convert it to the desired format with the <code>toLocaleDateString()</code> method of the <code>Date</code> object:

<pre><code>// Using the current date/time
let now_local = new Date();
let now_utc = new Date();

// Adding the UTC offset to create the UTC date/time
now_utc.setMinutes(now_utc.getMinutes() + now_utc.getTimezoneOffset())

// Specify the format you want
let date_format = {};
date_format.year = 'numeric';
date_format.month = 'numeric';
date_format.day = '2-digit';
date_format.hour = 'numeric';
date_format.minute = 'numeric';
date_format.second = 'numeric';

// Printing the date/time in UTC then local format
console.log('Date in UTC: ', now_utc.toLocaleDateString('us-EN', date_format));
console.log('Date in LOC: ', now_local.toLocaleDateString('us-EN', date_format));
</code></pre>

I'm creating a date object defaulting to the local time. I'm adding the UTC off-set to it. I'm creating a date-formatting object. I'm displaying the UTC date/time in the desired format:

Using NodeJS, I want to format a <code>Date</code> into the following string format:

<pre><code>var ts_hms = new Date(UTC);
ts_hms.format("%Y-%m-%d %H:%M:%S");
</code></pre>

How do I do that?

How to format a UTC date as a `YYYY-MM-DD hh:mm:ss` string using NodeJS?

 使用NodeJS，我想格式化一个 转换为以下字符串格式： var ts_hms = new Date(UTC);ts_hms.format("%Y-%m-%d %H:%M:%S"); 我该怎么做呢？
