Django/Foundation CSS Accordion Not Displaying Contents

"created" value of TimeStampedModel is showed diffrently
I am creating the review part in my Django project. When the new review is created, the page will show the new review without redirect(with javascript), and after the page is redirected it will show the same review from DB. but the there is some difference between the created time of new review from javascript and the other one from DB. On the template, the review from DB is showed exactly my local time. But the new review created from javascript that takes the value of "created" from the backend, is different from the same review form DB after redirect. for example, 27-November-2021-00:11 (after the new review is rendered with JS without redirect) 27-Novembre-2021-09:47 (after redirecting, the new review from DB) It seems to me maybe the first one is not applicated UTC time. but printing the value of "created", the console shows 2021-11-27 00:49:57.878138+00:00 the hours are the same as the first one but the minutes are the same as the last one... I can't understand. because these two values are from the same thing, "created" of the TimeStamped Model. How could I make this value the same? models.py class TimeStampedModel(models.Model): """TimeStampledModel Definition""" created = models.DateTimeField( auto_now_add=True ) updated … -
