Moment.js moment().local() Method

The moment().local() method is used to specify that the given Moment object’s timezone would be displayed in the local timezone of the user. An optional parameter can be passed that preserves the current time value and only changes the timezone to the local one.

Syntax:

moment().local( Boolean );

Parameters: This method accepts a single parameter as mentioned above and described below:

• Boolean: It is a boolean value that specifies whether the timezone would be changed without changing the actual time itself.

Return Value: This method returns the Moment object with the new timezone.

Note: This will not work in the normal Node.js program because it requires an external moment.js library to be installed globally or in the project directory.

Moment.js can be installed using the following command:

Installation of moment module:

npm install moment

)
console.log(
