moment.js timezone get milliseconds

Question

I'm trying to get number of days passed. I'm storing epoch (milliseconds) for date. I'm reading startDate from database (date value of first record) in milliseconds and I want to find current epoch in specified timezone.

I tried this:

var startDate = rows[0]['MIN_DATE'];
var endDate = moment().tz("America/New_York");

Then to calculate difference, I used:

var oneDay = 24 * 60 * 60 * 1000;
var daysCount = Math.ceil((endDate - startDate) / (oneDay));

The value of startDate is:

1522821600000 which is: Wednesday, April 4, 2018 2:00:00 AM GMT-04:00 DST

The value of endDate is:

Moment_d: Wed Apr 04 2018 22:24:45 GMT-0400 (EDT)_isAMomentObject: true_isUTC: true_isValid: true_locale: Locale_offset: -240_pf: Object_z: Zone__proto__: Object

The value of daysCount is 2, how? How can I get milliseconds instead of object from:

moment().tz("America/New_York");

To directly answer your question, use .valueOf() to get the value of moment.tz("America/New_York")

var endDate = moment.tz("America/New_York").valueOf()

I'm having difficulty understanding your question, but I believe you're trying to get the difference between the days considering the correct timezone. The following gives an accurate result using .diff() (https://momentjs.com/docs/#/displaying/difference/)

var timeZone = "America/New_York"
var startDate = 1522821600000
var momentStartDate = moment.tz(startDate,timeZone)
var momentEndDate = moment.tz(timeZone)

alert(momentEndDate.diff(momentStartDate, 'days') );

Use fromNow() function. It is very straight-forward.

Do like this :

moment(date).fromNow();

It will give you number of days passed if date is past as well as number of days to go if date is future.

Below are is example:

var date = 1522821600000; // your date

console.log(moment(date).fromNow());

Solved this with following statement:

var endDate = moment().tz("America/New_York").valueOf();
