I'm working on an app that returns EST time. I want to convert EST time to the user's local timezone.
eg: EST: 2022-03-23T21:00:00.000Z
PKT: 2022-03-24T06:00:00.000Z
Sydeny: 2022-03-24T12:00:00.000Z
I think time zones will be selected by default with your location ( local one ). However to convert it into another one you can use moment js library.
const moment = require('moment-timezone')
const start = moment.tz("2021-12-08T10:00:00", "UTC") // original timezone
console.log(start.tz("America/Los_Angeles").format())
console.log(start.tz("Asia/Calcutta").format())
console.log(start.tz("Canada/Eastern").format())
