Javascript Date.getTime() returns NaN in internet Explorer 11 only

I have a below JavaScript function which returns time from the full date.
function f() {
var monthNames = ["Jan", "Feb", "Mar", "Apr", "May", "Jun",
"Jul", "Aug", "Sept", "Oct", "Nov", "Dec"
];
d = new Date();
var utcOffset = -6;
var utc = d.getTime() + (d.getTimezoneOffset() * 60000);
var localDate = new Date(utc + (3600000 * (utcOffset + 1)));
var fullDate = localDate.getDate() + ' ' + monthNames[localDate.getMonth()] + ' ' + localDate.getFullYear() + ' ' + localDate.toLocaleTimeString();
var now = new Date(fullDate).getTime();
return now;
}
In all browsers it returns expected output but not for Internet Explorer 11, as it returns NaN.
Please suggest changes to get the expected output.

Want to get the name of month in form of Jan, Mar, .... Dec. using JS

var today = new Date();
//$('#timeStampID').val(today.getFullYear() + '-' +
('0' + (today.getMonth() + 1)).slice(-2) + '-' + ('0' +
today.getDate()).slice(-2));
$('#timeStampID').val(String(('0' +
today.getDate()).slice(-2)) + ' ' +
String(('0' + (today.getMonth() + 1)).slice(-2)) + ' ' +
String(today.getFullYear()));
Here i'm getting output on input filed as : 23 04 2018 but i want to show Apr in place of 04 i.e name of the month

Unfortunately, there isn't a method for this built into the Date object. But you can do something like this:
var months = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"];
var monthName = months[today.getMonth()];

Stackoverflow style date format

How to format the javascript Date object the way stackoverflow does it.
For example. Aug 23 '10 at 23:35
This is what I tried.
new Date(val.replace(' ','T')+'Z').toString().split('GMT')[0]
This works cross browser. But doesn't look neat.

function formatDate(date) {
var monthNames = [
"Jan", "Feb", "Mar",
"Apr", "May", "Jun", "Jul",
"Aug", "Sep", "Oct",
"Nov", "Dec"
];
var day = date.getDate();
var monthIndex = date.getMonth();
var month = monthNames[monthIndex];
var year = date.getFullYear().toString().substring(2,3);
var hours = date.getHours();
var minutes = date.getMinutes();
return month+' '+day+" '"+year+' at '+hours+':'+minutes;
}

Try this:
var date = new Date();
var formattedDate =
(date.toLocaleString("en-us", { month: "long" })) + " " +
date.getDate() + " '" + (date.getFullYear() % 100);
var formattedTime = date.getHours() + ':' + date.getMinutes();
alert( formattedDate + " at " + formattedTime );
Here's a JSFiddle.

Show clock with CST time in html page using JavaScript

How to show clock with CST time format in HTML page using JavaScript? It should show exact CST time in this format "02 Jul 2015 10:34:45 PM"

Not sure if there is a better way but i was unable to find anything. This works though.
var monthNames = ["Jan", "Feb", "Mar", "Apr", "May", "Jun",
"Jul", "Aug", "Sept", "Oct", "Nov", "Dec"
];
d = new Date();
//set the offset
var utcOffset = -6;
//get utc
var utc = d.getTime() + (d.getTimezoneOffset() * 60000);
//create new date adjusting by the utcOffset to get local date/time
var localDate = new Date(utc + (3600000 * (utcOffset+1)));
//check if one character if so format as two by adding leading 0.
var formatDay = (localDate.getDate().length > 1) ? localDate.getDate() : '0' + localDate.getDate();
//string everything together
var fullDate = formatDay + ' ' + monthNames[localDate.getMonth()] + ' ' + localDate.getFullYear() + ' ' + localDate.toLocaleTimeString();
$('#div1').html(fullDate);

JavaScript - List of last 12 Months

I have an Angualr service that lists out 12 months and year from the current month:
JS:
app.factory('12months', function() {
return {
getMonths: function() {
var date = new Date();
var months = [],
monthNames = [ "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec" ];
for(var i = 0; i < 12; i++) {
months.push(monthNames[date.getMonth()] + ' ' + date.getFullYear());
date.setMonth(date.getMonth() - 1);
}
return months;
}
};
});
Which output is:
Oct 2014, Sep 2014, Aug 2014 etc etc
How can i modify this to display the day too, so:
21 Oct 2014, 21 Sep 2014, 21 Aug 2014 etc etc

How about using the date filter
var app = angular.module('my-app', [], function() {
})
app.controller('AppController', ['$scope', '12months',
function($scope, tmonths) {
$scope.tmonths = tmonths.getMonths();
}
])
app.factory('12months', ['dateFilter',
function(dateFilter) {
return {
getMonths: function() {
var date = new Date();
var months = [];
for (var i = 0; i < 12; i++) {
months.push(dateFilter(date, 'dd MMM yyyy'));
date.setMonth(date.getMonth() - 1)
}
return months;
}
};
}
]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="my-app" ng-controller="AppController">
<pre>{{tmonths | json}}</pre>
</div>

append date to string:
app.factory('12months', function() {
return {
getMonths: function() {
var date = new Date();
var months = [],
monthNames = [ "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec" ];
for(var i = 0; i < 12; i++) {
months.push(date.getDate()+ ' ' +monthNames[date.getMonth()] + ' ' + date.getFullYear());
}
return months;
}
};
});

You can just concatenate the day to the string in the months array:
So instead of this:
months.push(monthNames[date.getMonth()] + ' ' + date.getFullYear());
Do this:
months.push(date.getDate() + ' ' + monthNames[date.getMonth()] + ' ' + date.getFullYear());

You can date in jquery
var date = new Date();
date.getDate() //output:- 21

Add Total days in the days Array:
app.factory('twelvemonths', function() {
return {
getMonths: function() {
var date = new Date();
var months = [],
monthNames = [ "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec" ];
days=[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31];
for(var i = 0; i < 12; i++) {
months.push(days[date.getDate()]+ ' ' +monthNames[date.getMonth()] + ' ' + date.getFullYear());
}
return months;
}
};
});

If you want to use your function you could change the line to
months.push(date.getDate() + ' ' monthNames[date.getMonth()] + ' ' + date.getFullYear());
