Different date time format

Using Django
1

Greetings,
When page is loading view, taking date from mysql db model it shows this datetime format:

Oct. 7, 2021, 2:23 a.m.

After AJAX kickin and refresh the table the same model it shows this:

2021-10-06T23:23:45Z

I know whats happening, but still confused.
Can somebody tell me what and where is the right way to make a default datetime format?
For whole django+ajax+java…ALL

settings.py

LANGUAGE_CODE = 'en-us'
TIME_ZONE = 'UTC'
USE_L10N = True
USE_TZ = True
DATETIME_FORMAT = '%Y-%m-%d %H:%M:%S'

part of ajax:

        for (var key in response.tblcnt)
        {
         $("#tblcnt").append(
            `
            <tr>
                         <td>${ response.tblcnt[key].dt_first }</td>
                      </tr>`
            
          )
        }

models

    dt_first = models.DateTimeField('dt_first',blank=True)

Thank you for any pointers.
I found format_input which is not what i want,for now at least :smiley:

UPDATE 1:
For regular view this is working:

<td>{{ i.dt_first|date:"Y.m.d H:i:s" }}</td>

output:

2021.10.07 02:23:45

Still need ajax

Okay so after 5hours finaly got it.
Javascript/ajax

         var dt_firstold = new Date(response.tblcnt[key].dt_first);
         var dt_first = moment(dt_firstold).format("YYYY.MM.DD HH:mm:ss");

HTML

<td>{{ i.dt_first|date:"Y.m.d H:i:s" }}</td>
