Detect timezone abbreviation using JavaScript

Question

I need a way to detect the timezone of a given date object. I do NOT want the offset, nor do I want the full timezone name. I need to get the timezone abbreviation.

Answer 1

import { tz } from 'moment-timezone';
import * as moment from 'moment';

const guess = tz.guess(true);    // "Asia/Calcutta"
const zone = tz.zone(guess);     // return Zone object 
zone.abbr(new Date().getTime())  // "IST" 
// once u pass timestamp it'll return timezone abbrevation.
