If I set default moment time zone with moment.tz.setDefault(), is there a way to later retrieve the current default time zone?
Example:
const moment = require('moment-timezone');
moment.tz.setDefault('Asia/Tokyo');
console.log(moment.tz.getDefault()); // TypeError: moment.tz.getDefault is not a function
console.log(moment.tz.default); // undefined
console.log(moment.tz.guess()); // America/New_York (my local timezone)
console.log(moment.tz.guess(true)); // America/New_York
// => I want something that will return "Asia/Tokyo"
This is different from the suggested duplicate because I don't want the browser's time zone, I specifically want to know what (if anything) moment.tz.setDefault() was set to.
You can achieve that by moment.defaultZone.name:
const moment = require('moment-timezone');
moment.tz.setDefault('Asia/Tokyo');
console.log(moment.defaultZone.name)
Output:
Asia/Tokyo
Update after @Kip comment
moment.defaultZone is undefined, so use moment.defaultZone?.name to be safe.moment().format('ZZ') which returns "+0900" in Tokyo time.
