date present in database 2020-10-16 09:14:31.000 is coming NaN-undefined-NaN NaN:NaN:NaN AM in internet explorer while retriving in knockout js but it coming properly in google chrome kindly help for same

What I have tried:

JavaScript

self.LastSaveDate = ko.observable();
            if (item.LastSaveDate != '' && item.LastSaveDate != null && item.LastSaveDate != 'undefined') {


                self.LastSaveDate(formatDate(new Date(item.LastSaveDate + 'UTC').toString()));
            } else {
                self.LastSaveDate('');
            }

JavaScript

function formatDate(dt) {
    var current_datetime = new Date(dt);
    var hours = current_datetime.getHours() > 12 ? current_datetime.getHours() - 12 : current_datetime.getHours();
    var am_pm = current_datetime.getHours() >= 12 ? "PM" : "AM";
    hours = hours < 10 ? "0" + hours : hours;
    var minutes = current_datetime.getMinutes() < 10 ? "0" + current_datetime.getMinutes() : current_datetime.getMinutes();
    var seconds = current_datetime.getSeconds() < 10 ? "0" + current_datetime.getSeconds() : current_datetime.getSeconds();
    time = hours + ":" + minutes + ":" + seconds + " " + am_pm;
    var formatted_date = current_datetime.getDate() + "-" + months[current_datetime.getMonth()] + "-" + current_datetime.getFullYear() + ' ' + time;
    return formatted_date;
    
}

var months = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"];

IE start to be a little dated, even MS don't use it anymore.
You may need different code for both navigators.
To understand what is going on, only 1 solution, the debugger or debugging techniques.
Navigating the F12 Developer Tools Interface (Internet Explorer) | Microsoft Docs[^]

Your code do not behave the way you expect, or you don't understand why !

There is an almost universal solution: Run your code on debugger step by step, inspect variables.
The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't know what your code is supposed to do, it don't find bugs, it just help you to by showing you what is going on. When the code don't do what is expected, you are close to a bug.
To see what your code is doing: Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute.
