Re-open #4803: moment().format() incorrect on older browsers

[Unsfer]

re-open #4803
Tried on the latest (2.24.0) version, still the same result

var date = "1983-04-01";
var ruDate = moment(date, 'YYYY-MM-DD').format('DD.MM.YYYY');
alert(date + " - " + ruDate);
// Output: "1983-04-01 - 31.03.1983"

@Unsfer What browser(s) are you testing in these days?

If these issues are due to bugs in the browse's implementation of Date, it won't be resolved in moment 2.x (see conversation in issue 4469)

[Unsfer]

Running on Chromium 35 and Firefox 45.9.0
And sadly our env tied on old browsers

@marwahaha Is it just abandoned?

Tested on last available version, still the same result

https://jsfiddle.net/jv9tzmxr/

var date = "1983-04-01";
var ruDate = moment(date, "YYYY-MM-DD").format("DD.MM.YYYY");
alert("Moment version: " + moment.version + ". \nTest: " + date + " - " + ruDate);
// Output:
// Moment version: 2.25.3. 
// Test: 1983-04-01 - 31.03.1983

I cannot reproduce this:

What time zone or locale are you in?

[Unsfer]

The bug only reproduced on browsers mentioned above.

Locale/timezone: ru +0400

The reason probably #4803 (comment)

[marwahaha]

As ashsearle mentioned, if they are related to browser implementation of Date, they cannot be fixed by Moment 2.x

Sorry you are experiencing this issue.
