Moment.js - how to get user time zone?

Question

I want to set current time zone with moment.js for user that runs my app. My problem is that many of momentjs question posted here have method called tz but I can't see it now in 2020.

Format date in a specific timezone

With that method you can set this:

moment().tz('America/Phoeinx')

But I don't want to set this manually. I found utc method but it returns me timezone +0000.

How to set current time zone with momentjs in 2020?

Answer 1

Ok I found an answer, all that we need is just get current utcOffset from momentjs library:

const currentUtcOffset = moment().utcOffset()

and pass it to utc method

moment(date).utc(currentUtcOffset).toISOString()

Now everything works perfect.
