Here’s another way how to get the time using Date.getTime() method in JavaScript.

With the setTime() method, developers can easily change the time of an existing date object.

This allows for various operations like adding or subtracting time intervals or setting a specific time of the day.

Here’s an example code to illustrate it:

const currentDate = new Date();
currentDate.setTime(currentDate.getTime() + 60 * 60 * 1000); // Just add one hour
console.log(currentDate);

What is new date () getTime () in JavaScript?

The new Date() function creates a Date object that represents the current date and time.

If you call the getTime() method on this object, it will give you the number of milliseconds since a specific reference point.

let time = new Date().getTime();
console.log(time); 

Output:

1687583966853

How to get current Date and time in JavaScript?

JavaScript provides a convenient way to get the current date and time through the new Date() object.

By utilizing the browser’s time zone, it presents the date in a detailed textual format, which encompasses the precise date, time, and corresponding time zone information.

const date = new Date();
console.log(date);

Output:

2023-06-24T04:57:28.283Z

Example code if you want to get the current date alone

JavaScript offers the toLocaleDateString() or toLocaleString() method, which is a useful tool for developers to format dates according to different regions and personal preferences.

With this method, developers can easily customize how dates are displayed, whether it’s showing only the date, only the time, or a combination of both, based on their specific needs.

const date = new Date()

const todaysDate = date.toLocaleDateString()
console.log(todaysDate)

Output:

6/24/2023

Alternatively, you can use the following code:

const currentDate = new Date();
const options = { weekday: 'long', year: 'numeric', month: 'long', day: 'numeric' };
const formattedDate = currentDate.toLocaleString('en-US', options);
console.log(formattedDate);

Output:

Saturday, June 24, 2023

Here’s the example code of JavaScript datetime and gettime.

const date = Date()

console.log(date);

Output:

Sat Jun 24 2023 05:09:29 GMT+0000 (Coordinated Universal Time)
