Indiana is a perfect example of such a situation. The fact that the United States is divided into multiple time zones also complicates things like broadcasts and live events. The structure of how we tell time may not be perfect, but it is a necessity when it comes to calculating for the rotation of the Earth and the apparent changes in time across the vast land mass that is the United States.
This favoritism has led to many different changes and modifications to the way we handle broadcast scheduling.

Here is the solution for finding the remote countries TimezoneOffset by just passing the timezone to the function. This uses the timeZoneName property of Intl. This not only gets the formatted GMT offset time i. GMT-5 , but also the colloquial name of the timezone i. Central Daylight Time. The only thing this method doesn't do is get the IANA timezone.
I recommend the top answer for that. As far as I'm aware, DateTimeFormat doesn't have a way to do custom formatting, hence the use of formatToParts , which seems to be the only reliable way to get just the timezone. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

I'm figting the same problem now. Here is an interesting approach. The title asks for timezone, while the text asks for GMT offset. These are 2 different things.

However IE11 and latest Firefox both return undefined for the timeZone property. I have tested in now with Chrome 58, Edge 40 and Firefox 53 - it works will all of them.
