Hello everybody,
I have a django web app, in my app i want to show in the page where the
time information is, with user timezone.

I have a form with start_time and end_time(Timefield) user send this with a
specific timezone(Berlin/Europa) after this when a user go to the page, the
user should see the page with his own timezone.

I use Django 2.1 with postgresql database.

Thanks for any recommendation!
Regards,
Deniz

Hello,
I think you can use "request.META" django. (request.META['TZ']). It is
timezone user submit request.

:D

From docs: "...there’s no equivalent of the Accept-Language HTTP header
that Django could use to determine the user’s time zone automatically.
Instead, Django provides time zone selection functions
<https://docs.djangoproject.com/en/dev/ref/utils/#time-zone-selection-functions>.
Use them to build the time zone selection logic that makes sense for you."

There is two paths.
First. You can store time on the server in UTC, detect user timezone and
then do conversion to this timezone on your backend. You can also look at
https://docs.djangoproject.com/en/dev/topics/i18n/timezones/#localtime
Second path is that you can do time conversion on the frontend using
whatever you like JS library to do this work. But in both cases you should
determine users timezone yourself or ask user in which TZ he is.

Hello Vovk Donets,
thanks for your answer.

In my app, i can not ask the user for timezone because its impossible.I
send a screen shot from app you can better understand me.

[image: image.png]
this is for a Internet TV.The user can be from any timezone.
I want just use django(python) make this possible.
In your answer you say there is two way make this, but i don't understand
1. way(*detect user timezone and then do conversion to this timezone on
your backend. *)


*Settings.py*
TIME_ZONE = 'UTC'

USE_I18N = True

USE_L10N = True

USE_TZ = True

*my model.py*
class Guide(models.Model):

episode=models.ForeignKey(Episode,on_delete=models.CASCADE,verbose_name=_('Program'))
slug=models.SlugField(max_length=100 ,unique=True,allow_unicode=True)

create_date=models.DateField(default=timezone.now,verbose_name=_('Publishing
Date'))
start_time=models.TimeField(default=timezone.now,verbose_name=_('Start
Time'))
end_time=models.TimeField(default=timezone.now,verbose_name=_('End
Time'))
publish=models.BooleanField(default=True,verbose_name=_('Publish'))

i use in time field *default=timezone.now *but i m not sure* i*f should use
*default=datetime.datetime.now*
