why the time in Django rest framework is not correct

why when I updated entry in the database the updated time field in the model 

updated = models.DateTimeField(auto_now=True)

is updated correctly according to timezone in my settings file but when it appeared in the Django rest Framework terminal it is shifting back 3 hours

The following code is for the Model:

class hashtag(models.Model):
    tag = models.CharField(max_length=120)
    count = models.IntegerField(default=0,blank=True)
    timestamp = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)

the following code is for DRF:

last_update = serializers.SerializerMethodField()
class Meta:
    model =  hashtag
    fields = [
        'id',
        'tag',     
        'date_display',
        'last_update',
        'timestamp',
        'updated'

    ]
def get_last_update(self,obj):
    return obj.updated.strftime('%b %d  %I:%M %p')

By using SerializerMethodField you are out of the reach for DRF to properly handle your timezone settings.

So either stick the burden to DRF and use a source to map updated to last_update :

last_update = serializers.DateTimeField(source='updated', format='%b %d  %I:%M %p')
class Meta:
    model =  hashtag
    fields = [
        'id',
        'tag',     
        'date_display',
        'last_update',
        'timestamp',
        'updated'
    ]

Or handle the timezone yourself:

def get_last_update(self,obj):
    tz = timezone.get_current_timezone()
    return obj.updated.astimezone(tz).strftime('%b %d  %I:%M %p')
