Detect timezone abbreviation using JavaScript

Question

I need a way to detect the timezone of a given date object. I do NOT want the offset, nor do I want the full timezone name. I need to get the timezone abbreviation.

Answer 1

try {
    result = /.*\s(.+)/.exec(date.toLocaleDateString(navigator.language, {timeZoneName:'short' }))[1];
} catch(e) {
    result = (new Date()).toTimeString().match(new RegExp("[A-Z](?!.*[\(])","g")).join('');
}

console.log(result);
