How to set server time in Node.js

I would like to set (mock) my custom time to the Node.js server for testing purposes. Something like this:

console.log(new Date());
// Sat Jun 30 2018 20:00:00 GMT+0100
// ^^
someFunctionToSetTime('Sat Jun 30 2018 12:00:00 GMT+0100')
// ^^
console.log(new Date());
// Sat Jun 30 2018 12:00:00 GMT+0100
// ^^


How do I do this?

P.S. I don't really want to fake the Date class.

Date

Date

var d = new Date(2018,06,30, 12, 00);

Just monkey patch the Date constructor:

let now = 'Sat Jun 30 2018 12:00:00 GMT+0100';

{
const oldDate = Date;
Date = function(...args) {
if(args.length) {
return new oldDate(...args);
} else {
return new oldDate(now);
}
};
}


First option : Without external modules you can use this to get timezone Date and time in node.js
var myDate = new Date().toLocaleString('en-US', {
timeZone: 'Europe/Paris'
});

var myDate = new Date().toLocaleString('en-US', {
timeZone: 'Europe/Paris'
});

Second option : Use momentjs timezone witch allows you to set your location and more... just check the documentation.
