Moment js - get date without considering time zone

问题

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

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();

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');

I don't know if you are going to like my solution but just give it a thought that if you want to ignore timezone then why not from the string itself. Don't downvote if you don't like it. 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();
}

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);
