Generate date format in javascript with locale appended

Question

A 3rd API(mediamath,FYI) is requiring the following date format to set the date to 21 march EST :

2019-03-21T00:00:00+America/New_York

How can I generate this string directly using the javascript date object?

Thank you.

Are you trying to generate that date string based on the current local time and time zone? Or is it based on some other input? — benvc, Mar 14 '19 at 20:45
Current local time and time zone . I want to set the end_date to month end 11.59pm EST and start date to current time and date EST. — zacurry, Mar 15 '19 at 08:10

You can calculate moment's

moment().format(moment.HTML5_FMT.DATETIME_LOCAL) // 2019-03-14T22:43

and

moment.tz.guess() // Asia/Yerevan

If you can use the moment and moment-timezone libraries, here is some sample code that will take your input and calculate the desired output.

let moment = require('moment-timezone');  

let rawInput = "2019-03-21T00:00:00+America/New_York";       
let separatorIndex = rawInput.indexOf("+");
let time = rawInput.substring(0, separatorIndex);
let zone = rawInput.substring(separatorIndex + 1);
let calculatedMoment = moment.tz(time, zone);
let yourOutput = calculatedMoment.format("DD MMM z");

//yourOutput now has "21 march EDT"

my input will be in local time zone , the output needs to be in EST. — zacurry, Mar 15 '19 at 08:12
