How to extract only time from the date which is present in ISO format? I tried this:

var d = new Date('1970-01-15T03:32:12.000Z'); //ISO-8601 formatted date returned from server
console.log(d.getTime());// 1222332000

Expected op is : 03:32:12

Since your server returns an ISO-8601 formatted date which has a predefined format, you can convert it to ISO string using toISOString() and then get the substring of the time value:

var d = new Date('1970-01-15T03:32:12.000Z'); 
console.log(d.toISOString().substr(11,8));

Date.getTime() returns the time in UNIX epoch format. https://en.wikipedia/wiki/Unix_time

To access only the parameters you are interested in, you can use Date.getMinutes(), Date.getMinutes(), etc. See docs on MDN: https://developer.mozilla/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date

Note: Do not forget to spend one thought on time zones when you work with Date 's time, especially when your app runs in different regions.

You have to manually build the time string using Date.prototype methods: getHours, getMinutes and getSeconds

Or use moment.js library.

Date.getTime() gives you the unix timestamp, which is the number of seconds since january 1st 1970;

The getTime() method returns the numeric value corresponding to the time for the specified date according to universal time.

from MDN

You need to format the date yourself, either by concatenating the output of the Date.getHours(), Date.getMinutes() and Date.getSeconds() methods, or by using one of the predefined formatting functions, like Date.toTimeString(). Checkout the docs to pick your choice.

You can use getHours(),getMinutes() and getSecondes(). Then you can use it with strings or objects.

Try the following:

d.toTimeString().split(' ')[0]

You can use moment.js to parse whatever format you like.

If you think moment.js is too big, there's another library call dayjs. The same fashion API but just 2KB. (Unfortunately, you can't do UTC time with dayjs yet.)

Update: Thanks kun for notifying the updates. You can now use UTC with dayjs plugin since v1.8.9.

var d = new Date('1970-01-15T03:32:12.000Z');
console.log(moment(d).utc().format('HH:mm:ss'));
dayjs.extend(dayjs_plugin_utc)
console.log(dayjs(d).utc().format('HH:mm:ss'));
