Where is timezone stored?

Question

Django

Hello to all toasters.
I stumbled upon a problem and thought - where to store the user's time zone for the site?
There are a couple of options in my head:
1) In the base, but it's too expensive - constantly climb into the base for them.
2) Use jstz to keep it in Cookie.
3) There will be a base on Redis - you can store it in some hash table.
Where do you store? And why?

Answer 1

if you have less than a million users per month, then you can safely store no plugs in the database

Answer 2

timezone is part of the user profile. therefore, uniquely in the database and in relation to the user
