Moment js - get date without considering time zone

Question

I did read different StackOverflow posts and they suggested to use .utc from moment but it doesn't work

Note: I am on PST zone

const start = '2018-06-10T21:00:00-04:00';
const end = '2018-06-10T23:00:00-04:00';
const noconversion = moment.utc(start).format('MM/DD/YYYY');
const converted = moment(end).format('MM/DD/YYYY');

Current output:

noconversion - 2018-06-11

converted - 2018-06-11

Output expected: 06/10/2018 just fetch date from date provided

CODEPEN Link

const date = '2018-06-16T00:00:00-04:00';
const oldConversion = moment(date).format('MM/DD/YYYY');
const newConversion = moment.parseZone(date).format('MM/DD/YYYY');
 
alert('********oldConversion**********'+ oldConversion);
alert('********newConversion**********'+ newConversion);

Why not make a custom function to do it? Does it really have to be with moment.js? — Sookie Singh, Jul 25 '18 at 21:08
I think: new Date also considers timezone. How can I make custom function, With all the cases — user2936008, Jul 25 '18 at 21:18

Have you tried parseZone?

moment.parseZone(end).format('MM/DD/YYYY');

That should keep your UTC offset applied. You can then also calculate the UTC offset, if you wanted to save that:

moment.parseZone(end).format('MM/DD/YYYY').utcOffset();

I did try it I did had the same issue in one of the time zone. I will check again – user2936008 Jul 25 '18 at 21:20
@KamalakannanJ from https://momentjs.com/docs/#/parsing/parse-zone/ seems like there is some conversion going on – user2936008 Jul 25 '18 at 21:28
I did take this approach as it resolves EST/PST issue. – user2936008 Jul 25 '18 at 21:41

The solution I'm suggesting will ignore the timezone itself. It always take only the date. It might be a complex way to do it, but it always works for you.

const start = '2018-06-10T21:00:00-04:00'.split('-').slice(0, -1).join('-');
const end = '2018-06-10T23:00:00-04:00'.split('-').slice(0, -1).join('-');
const noconversion = moment(start).format('MM/DD/YYYY');
const converted = moment(end).format('MM/DD/YYYY');

What if the timezone is not provided? This will fail in that case. I wouldn't take that risk. I would never muck with the string provided. – user2936008 Jul 25 '18 at 21:32

If you want to ignore timezone then why not from the string itself? This is just an out of the box thinking.

function convertToDate(date_string) {
    var date = date_string.indexOf('T') > -1 ? new Date(date_string.split('T')[0]) : date_string.indexOf(' ') > -1 ? new Date(date_string.split(' ')[0]) : new Date(date_string.substring(0,10));
    return (date.getMonth() + 1) + "/" + date.getDate() + "/" + date.getFullYear();
}

OR

function convertToDate(date_string) {
    var date = date_string.indexOf('T') > -1 ? date_string.split('T')[0].split('-') : date_string.indexOf(' ') > -1 ? date_string.split(' ')[0].split('-') : date_string.substring(0,10).split('-');
    return date[1] + "/" + date[2] + "/" + date[0];
}

const start = '2018-06-10T21:00:00-04:00';
const converted = convertToDate(start);

It won't fail even there is no timezone as I am splitting with **T** separator which is in all date standards. – Sookie Singh Jul 25 '18 at 21:36
Still I am afraid to use string split approach – user2936008 Jul 25 '18 at 21:38
I have added one more function which uses Date function. – Sookie Singh Jul 25 '18 at 21:50
