php - Setting timzone at global level after user login -


my application has users various timezones. i've set settings page user can save timezone preference.

the problem

i've login controller in i'm fetching logged in user's timezone value , setting using:

date_default_timezone_set('europe/berlin'); // value pulled database

but redirect "login" controller "dashboard" controller, timezone being set original default value of america/chicago.

i verified using 

date_default_timezone_get(); // prints "america/chicago"

so should put timezone setting code effects entire application?

ps: know index.php file or config.php file choice @ places, won't have user's timezone value retrieved database.
