Create a Date with a set timezone without using a string representation

Question

I have a web page with three dropdowns for day, month and year. If I use the JavaScript Date constructor that takes numbers, then I get a Date obje

Answer 1

This worked for me. Not sure if it is a good idea though.

var myDate = new Date();
console.log('myDate:', myDate);   // myDate: "2018-04-04T01:09:38.112Z"

var offset = '+5';  // e.g. if the timeZone is -5

var MyDateWithOffset = new Date( myDate.toGMTString() + offset );   

console.log('MyDateWithOffset:', MyDateWithOffset); // myDateWithOffset: "2018-04-03T20:09:38.000Z"
