To change the timezone defaults of Moment.js, you can do the following:

  1. First, you need to install the Moment Timezone library using npm or include it directly in your HTML file: npm install moment-timezone or
  2. Import the Moment.js and Moment Timezone libraries in your JavaScript file or script tag: // CommonJS const moment = require('moment'); require('moment-timezone'); // ES modules import moment from 'moment'; import 'moment-timezone';
  3. Set the desired timezone as the default using the moment.tz.setDefault() method: moment.tz.setDefault('America/New_York'); // Set timezone to New York You can replace 'America/New_York' with any valid timezone identifier. You can find the list of supported timezone identifiers on the IANA Time Zone Database website.
  4. Now, when you use Moment.js functions, they will consider the default timezone you set. For example: const currentDate = moment(); // Current date/time in the default timezone const formattedDate = currentDate.format('YYYY-MM-DD HH:mm'); // Format the date/time console.log(formattedDate); // Output: 2022-12-14 09:30 (time in New York timezone)


By following these steps, you can change the default timezone for Moment.js and all subsequent operations will be based on the new timezone.
