How to set timezone in yii

When someone is reffering to application property or application config it means "root" config variable, in this case timeZone.

Config part:

<?php
// in protected/config/main.php
return array(
    'timeZone' => 'Asia/Calcutta'
    // Other configuration....
);

Example

project_folder/common/config/main.php

<?php
return [
    'vendorPath' => dirname(dirname(__DIR__)) . '/vendor',
    'components' => [
        'cache' => [
            'class' => 'yii\caching\FileCache',
        ],
    ],
    'timeZone' => 'Asia/Calcutta', //Time zone set
];

Configure at common/config/main.php:

'components' => [
    ...
    'formatter' => [
        'class' => 'yii\i18n\Formatter',
        'dateFormat' => 'php:j M Y',
        'datetimeFormat' => 'php:j M Y H:i',
        'timeFormat' => 'php:H:i',
        'timeZone' => 'Europe/Berlin',
    ],
