Yes, it's possible you need to calculate time zone offset and add then add to your date object time sample code is given below.
var d = new Date('2016-06-15 10:59:53.5055');
var timeZoneDifference = (d.getTimezoneOffset() / 60) * -1; //convert to positive value.
d.setTime(d.getTime() + (timeZoneDifference * 60) * 60 * 1000);
d.toISOString()

You can not remove timezone information when creating Date object -- this is a deficiency of the API.
The dates created via various Date APIs are parsed according to provided timezone (if the given method supports it), or if missing, they assume your local machine's timezone; then internally they're represented as dates relative to the UTC timezone.
Whenever you stringify a date, you implicitly invoke date.toJSON() which in turn invokes date.toISOString(), which stringifies to UTC-relative time (hence Z as the end which stands for Zulu i.e. UTC).
As far as I can tell there's no method that serializes to ISO-like string but using local timezone.
You could use low-level Date properties to write your own method which serializes back to the local timezone if you really need to, or you could use a library like date-fns. You could use moment library, but while very powerful, it's huge so be careful with it.
I was experimenting the same problem for a while. There is a timezone possible parameter to the date filter which I think should be the preferred solution, instead of making your own filter and append it. So, this is what worked for me:
{{ someAcceptedDateFormat | date : 'shortTime' : 'UTC' }}
I found this answer: Why does angular date filter adding 2 to hour?
Here is an example:
Just pipe another filter:
app.filter('utc', function(){
return function(val){
var date = new Date(val);
return new Date(date.getUTCFullYear(),
date.getUTCMonth(),
date.getUTCDate(),
date.getUTCHours(),
date.getUTCMinutes(),
date.getUTCSeconds());
};
});
In your template:
<span>{{ date | utc | date:'yyyy-MM-dd HH:mm:ss' }}</span>
I have a time stamp that I got from the server side.
The time before using the date pipe is : 2021-04-01T20:45:30.279+0000 ( html code:
<td mat-cell \*matCellDef="let element"> {{element.when }} </td> )
The time after I used date pipe: 01-Apr-2021 13:45:30
( html code: <td mat-cell *matCellDef="let element"> {{element.when | date: 'dd-MMM-yyyy HH:mm:ss'}} </td> )
The hour is different after using the date pipe. How can I stop it's conversion?
Thank you!
These folks are in the right track...I just want to say that working work dates in general and timezones specifically with JavaScript is awful.

If you don't want to automatically convert to your local timezone, then specify a timezone.
Hi all,
I've got myself in a bit of a pickle, and I'm hoping you kind souls can give me some advice.
I have an application where I want to show the time of an event in a specific time zone (this is neither UTC or local time). I've done this before using moment, but as it is in maintenance mode, I need to move on from it - I have currently been using Luxon, but this can be changed if other libraries are the answer.
My situation:
I start with a number, representing the number of milliseconds since the start of the epoch. This is read from a database (sample value: 1659222000000 - representing Saturday, 30 July 2022 23:00:00 in UTC/GMT)
I am in "Europe/London" time zone (Sunday, 31 July 2022 00:00:00)
I want to output the date/time for the "America/New_York" time zone (regardless of my browsers time zone: Saturday, 30 July 2022 19:00:00)
Does anyone have any bright ideas for how I can get it to show the time in New York instead of the time in London?
Thank you in advance!
You can create a custom filter for this, just convert the desired date without the timezone, for example:
myApp.filter('ignoreTimeZone', function(){
return function(val) {
var newDate = new Date(val.replace('T', ' ').slice(0, -6));
return newDate;
};
});
Check this fiddle: http://jsfiddle.net/ghxd6nom/
You can also use a library for this, like moment.js
Angular provides service '$filter'. We can inject this service on controller.
with the help of this service, we can format the date .
var dateFrom = $filter('date')(new Date(), "MM/dd/yyyy");
in this way, we can able to format the date with or without Timezone.
The return valus is string and we can convert the string into DateTime on Backend.
The otherway is to use library moment.js. This library provides better way of converting/formatting Dates.
check this blog , which provides angular date/time filtering & formatting.
Try this
d = new Date();
d.toLocaleString(); // -> "2/1/2013 7:37:08 AM"
d.toLocaleDateString(); // -> "2/1/2013"
d.toLocaleTimeString(); // -> "7:38:05 AM"
Take a look at the format string you supplied in relation to the output you got:
yyyy-MM-dd HH:mm:ss Z
2015-04-23 02:18:43 +0700
Note how each element of the format string corresponds to an element of the output?
Z represents the time zone. To get rid of it, just change the format string:
yyyy-MM-dd HH:mm:ss
You'll then get a time string like this:
2015-04-22 09:48:36
Since version 1.3.0 AngularJS introduced extra filter parameter timezone, like following:
{{ date_expression | date : format : timezone}}
But in versions 1.3.x only supported timezone is UTC, which can be used as following:
{{ someDate | date: 'MMM d, y H:mm:ss' : 'UTC' }}
Since version 1.4.0-rc.0 AngularJS supports other timezones too. I was not testing all possible timezones, but here's for example how you can get date in Japan Standard Time (JSP, GMT +9):
{{ clock | date: 'MMM d, y H:mm:ss' : '+0900' }}
Here you can find documentation of AngularJS date filters.
NOTE: this is working only with Angular 1.x
Here's working example
The 'Z' is what adds the timezone info. As for output UTC, that seems to be the subject of some confusion -- people seem to gravitate toward moment.js.
Borrowing from this answer, you could do something like this without moment.js:
controller
var app1 = angular.module('app1',[]);
app1.controller('ctrl',['$scope',function($scope){
var toUTCDate = function(date){
var _utc = new Date(date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate(), date.getUTCHours(), date.getUTCMinutes(), date.getUTCSeconds());
return _utc;
};
var millisToUTCDate = function(millis){
return toUTCDate(new Date(millis));
};
$scope.toUTCDate = toUTCDate;
$scope.millisToUTCDate = millisToUTCDate;
}]);
template
<html ng-app="app1">
<head>
<script data-require="angular.js@*" data-semver="1.2.12" src="http://code.angularjs.org/1.2.12/angular.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body>
<div ng-controller="ctrl">
<div>
utc {{millisToUTCDate(1400167800) | date:'dd-M-yyyy H:mm'}}
</div>
<div>
local {{1400167800 | date:'dd-M-yyyy H:mm'}}
</div>
</div>
</body>
</html>
here's plunker to play with it

Also note that with this method, if you use the 'Z' from Angular's date filter, it seems it will still print your local timezone offset.
I had a very similar problem a while ago: I wanted to store local dates on the server side (i.e. just yyyy-mm-dd and no timezome/time information) but since the Angular Bootstrap Datepicker uses the JavaScript Date object this was not possible (it serializes to a UTC datetime string in the JSON as you found out yourself).
I solved the problem with this directive: https://gist.github.com/weberste/354a3f0a9ea58e0ea0de
Essentially, I'm reformatting the value whenever a date is selected on the datepicker (this value, a yyyy-mm-dd formatted string, will be stored on the model) and whenever the model is accessed to populate the view, I need to wrap it in a Date object again so datepicker handles it properly.
Solution found here: https://github.com/angular-ui/bootstrap/issues/4837#issuecomment-203284205
The timezone issue is fixed.
You can use:
ng-model-options="{timezone: 'utc'}"To get a datepicker without timezone calculation.
EDIT: This solution does not work since version 2.x, however it did perfectly fine until then. I couldn't find a workaround and still am using version 1.3.3.
EDIT 2: As Sébastien Deprez pointed out in the comments below, this has been fixed in version 2.3.1. I just tested it and it works great.
<input
uib-datepicker-popup
ng-model="$ctrl.myModel"
ng-model-options="{timezone: 'utc'}">
