How do you change the timezone?

Is there any Codeigniter way to change the entire website time zone?
Thanks for your time :=)

I find that for changing the default time zone is best to add this

Code:

date_default_timezone_set('Australia/Queensland');

On to the config.php file Example I use Country/State

PHP Code:

<?php

defined('BASEPATH') OR exit('No direct script access allowed');

date_default_timezone_set('Australia/Queensland');

/*
|--------------------------------------------------------------------------
| Base Site URL
|--------------------------------------------------------------------------
|
| URL to your CodeIgniter root. Typically this will be your base URL,
| WITH a trailing slash:
|
|   http://example.com/
|
| If this is not set then CodeIgniter will try guess the protocol, domain
| and path to your installation. However, you should always configure this
| explicitly and never rely on auto-guessing, especially in production
| environments.

$config['base_url'] = ''; 


There's only one rule - please don't tell anyone to go and read the manual.  Sometimes the manual just SUCKS!
