How to get the offset time when the timezone is known using moment.js?

Question

Is there a way to know the offset time (how much ahead or behind the UTC/GMT), if I have the timezone value (for example 'America/Chicago') in momentjs or some other library in javascript?

Answer 1

You can grab the utcOffset.

const offset = moment().tz('America/Chicago').utcOffset();

console.log(`Offset in hours: ${offset / 60}`);
