Yii2 set timezone for DB connection

config.php

<?php

return [
  'components' => [
    'db' => [
        'class' => '\yii\db\Connection',
        'dsn' => 'mysql:host=127.0.0.1;dbname=demo',
        'username' => 'root',
        'password' => '',
        'charset' => 'utf8',
        'on afterOpen' => function($event) { 
          $event->sender->createCommand("SET time_zone='+00:00';")->execute(); 
        },
    ],
  ]
]

nice, and also we can use the UTC like this:

$event->sender->createCommand("SET time_zone = 'America/Manaus'")->execute();

America/Manaus is similar to -04:00

'America/Manaus'

i think it wont
