Remove Seconds/ Milliseconds from Date convert to ISO String

Question

I have a date object that I want to

1. remove the miliseconds/or set to 0
2. remove the seconds/or set to 0
3. Convert to ISO string

F

Answer 1

A non-library regex to do this:

new Date().toISOString().replace(/.\d+Z$/g, "Z");

This would simply trim down the unnecessary part. Rounding isn't expected with this.

Answer 2

A bit late here but now you can:

var date = new Date();

this obj has:

date.setMilliseconds(0);

and

date.setSeconds(0);

then call toISOString() as you do and you will be fine.

No moment or others deps.

Answer 3

let date = new Date();
date = new Date(date.getFullYear(), date.getMonth(), date.getDate());

I hope this works!!

Answer 4

You can use the startOf() method within moment.js to achieve what you want.

Here's an example:

var date = new Date();

var stringDateFull = moment(date).toISOString();
var stringDateMinuteStart = moment(date).startOf("minute").toISOString();

$("#fullDate").text(stringDateFull);
$("#startOfMinute").text(stringDateMinuteStart);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.11.2/moment.js"></script>
<p>Full date: <span id="fullDate"></span></p>
<p>Date with cleared out seconds: <span id="startOfMinute"></span></p>

Answer 5

We can do it using plain JS aswell but working with libraries will help you if you are working with more functionalities/checks.

You can use the moment npm module and remove the milliseconds using the split Fn.

const moment = require('moment')

const currentDate = `${moment().toISOString().split('.')[0]}Z`;

console.log(currentDate)

Answer 6

While this is easily solvable with plain JavaScript (see RobG's answer), I wanted to show you the Moment.js solution since you tagged your questions as "momentjs":

moment().seconds(0).milliseconds(0).toISOString();

This gives you the current datetime, without seconds or milliseconds.
