How can I get the current datetime in the format "2014-04-01:08:00:00" in Node?

Question

I need the current system datetime in the format "yyyy-mm-dd:hh:mm:ss".

https://stackoverflow.com/a/19079030/2663388 helped a lot.

new Date().toJSON() is showing "2014-07-14T13:41:23.521Z"

Can someone help me to extract "yyyy-mm-dd:hh:mm:ss" from "2014-07-14T13:41:23.521Z"?

Answer 1

Seems that there is no good way to do it with original code unless using Regex. There are some modules such as Moment.js though.

If you are using npm:

npm install moment --save

Then in your code:

var moment = require('moment');
moment().format('yyyy-mm-dd:hh:mm:ss');

That may be much easier to understand.

Answer 2

What about:

new Date().toString().replace(/T/, ':').replace(/\.\w*/, '');

Returns for me:

2014-07-14:13:41:23

But the more safe way is using Date class methods which works in javascript (browser) and node.js:

var date = new Date();

function getDateStringCustom(oDate) {
    var sDate;
    if (oDate instanceof Date) {
        sDate = oDate.getYear() + 1900
            + ':'
            + ((oDate.getMonth() + 1 < 10) ? '0' + (oDate.getMonth() + 1) : oDate.getMonth() + 1)
            + ':' + oDate.getDate()
            + ':' + oDate.getHours()
            + ':' + ((oDate.getMinutes() < 10) ? '0' + (oDate.getMinutes()) : oDate.getMinutes())
            + ':' + ((oDate.getSeconds() < 10) ? '0' + (oDate.getSeconds()) : oDate.getSeconds());
    } else {
        throw new Error("oDate is not an instance of Date");
    }
    return sDate;
}

alert(getDateStringCustom(date));

Returns in node.js: /usr/local/bin/node date.js 2014:07:14:16:13:10

And in Firebug: 2014:07:14:16:14:31

Answer 3

Install moment using

npm install moment --save

And in your code import the moment like this.

var moment = require('moment')
var created = moment().format('YYYY-MM-DD hh:mm:ss')

Answer 4

Though other answers are helpful I found the following code is working for me.

var d = new Date();
console.log(d.toJSON().slice(0,19).replace('T',':'));

The output on console is: 2014-07-15:06:10:16. I am using Node.js Express on Ubuntu.

Cleaner version of @Bernhard code using padStart and without deprecated getYear

function getCurrentDateTimeString() {
    const date = new Date();
    return date.getFullYear() + '-' +
        (date.getMonth() + 1).toString().padStart(2, '0') + '-' +
        date.getDate().toString().padStart(2, '0') + ':' +
        date.getHours().toString().padStart(2, '0') + ':' +
        date.getMinutes().toString().padStart(2, '0') + ':' +
        date.getSeconds().toString().padStart(2, '0');
}

console.log(getCurrentDateTimeString());

Answer 6

You can do it using toLocaleString() method in node.js

let date = new Date('2014-07-14T13:41:23.521Z');
console.log(date.toLocaleString('en-US')); 

//Converting current date time without timezone
date = new Date()
console.log(date.toLocaleString('en-US')); 

Answer 7

Explicity call each part of the Date:

function formatDate(date) {
    return [date.getFullYear(), date.getMonth() + 1, date.getDate()].join('-') + ':' +
        [date.getHours(), date.getMinutes(), date.getSeconds()].join(':');
}

function formatDatePart(part) {
    return part < 10 ? ("0" + part) : part;
}

You can see an example on this fiddle.

Answer 8

Correct way is this

var moment = require('moment');
moment().format('Y-M-D H:m:s');
