PostgreSQL saving date in 'Local time zone' while i set it to 'UTC' with Django

I m trying to save date in UTC format, but it being save in my localtimezone It is okay till Django view but after .save() it stores in database as 'localtimezone'

my setting.py

LANGUAGE_CODE = 'en-us' TIME_ZONE = 'UTC' USE_TZ = True 

model.py

class Career(models.Model): """ model for storing all leads from career section of front apps """ name = models.CharField(max_length=200) email = models.CharField(max_length=200) phone = models.CharField(max_length=20, blank=True, null=True) status = models.BooleanField(default=1) created_on = models.DateTimeField(null=True, blank=True) updated_on = models.DateTimeField(null=True, blank=True) class Meta: db_table = 'career_leads' 

my views file

class CareerFormApi(APIView): def post(self, request): career_serializer = CareerPostSerializer(data=request.data) career_data = request.data if career_serializer.is_valid(): career_serializer.validated_data['created_on'] = timezone.datetime.now() career_serializer.validated_data['updated_on'] = timezone.datetime.now() # I am geeting correct time zone here. print(timezone.datetime.now()) career_serializer.validated_data['status'] = True #after save i check my Database where it saved as my localtime zone career_serializer.save() return Response({ 'status': status_code.HTTP_201_CREATED, 'message': 'Detail has been saved successfully.' }, status=status.HTTP_201_CREATED) return Response(career_serializer.errors, status=status.HTTP_400_BAD_REQUEST) 

P.S. I have change my postgres timezone as well in to UTC like this

set timezone='UTC'; 

But it didn't work.
