how to use a fixed time zone in nodejs

To use a fixed time zone in Node.js, you can follow these steps:

Step 1: Install a Time Zone Library

Install a time zone library like moment-timezone using npm. This library provides functionality to work with time zones in Node.js.

Step 2: Require the Time Zone Library

Require the moment-timezone library in your Node.js file using the require keyword.

const moment = require('moment-timezone');

Step 3: Set the Time Zone

Use the moment.tz.setDefault() method to set the default time zone for your application. Pass the desired time zone as a parameter to this method.

moment.tz.setDefault('America/New_York');

Replace 'America/New_York' with the desired time zone identifier. You can find a list of time zone identifiers in the IANA Time Zone Database.

Step 4: Use the Fixed Time Zone

Now, when you work with dates and times using the moment library, it will use the fixed time zone you set as the default.

const now = moment(); // Get the current date and time in the fixed time zone

You can perform various operations on the now object, such as formatting, manipulation, and calculations, using the moment library.

That's it! You have successfully set and used a fixed time zone in Node.js.

Please note that the moment library is just one of many options available for working with time zones in Node.js. There are other libraries like luxon and built-in modules like Intl.DateTimeFormat that you can explore as well.
