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.

Using moment

moment().utcOffset(0, true).format()

From Javascript Date

var date = new Date();
Tue Sep 06 2021 00:00:00 GMT+0200

var isoDate = date.toISOString()
'2021-09-05T22:00:00.000Z'

var clearUTCDate = moment(date).utcOffset(0, true).format() 
'2021-09-06T00:00:00Z'

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>

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.

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

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'}">

If you don't want to automatically convert to your local timezone, then specify a timezone.
