Codeigniter timezone mysql settings

问题:

Just realised WHY my site is now showing all datetime variables as -1 hr... I'm using Codeigniter for the first time! (Never had this problem before)

So, I have included the following code in my main index.php file

/*
|---------------------------------------------------------------
| DEFAULT TIMEZONE
|---------------------------------------------------------------
|
| Set the default timezone for date/time functions to use if
| none is set on the server.
|
*/

if( ! ini_get('date.timezone') )
{
   date_default_timezone_set('GMT');
}

However, it's still showing as -1 hr, so I'm assuming I need to set some sort of default setting for MySQL...

I have included the following line of code in my model:

   function __construct()
    {
        // Call the Model constructor
        parent::__construct();
        $this->db->query("SET time_zone='+0:00'");
    }

Still no difference... Help!

My code is:

<h3><?=date('D, jS F @ g:ia', strtotime($row->datetime))?></h3>

The $row->datetime variable is nothing more than a DATETIME column value from my MySQL database. The echoed variable in view is ALWAYS 1 hour less than the value in my database...

My model code is:

function coming_up()
{
    $this->db->query("SET time_zone='+0:00'");
$query = $this->db->query('SELECT * FROM events1 WHERE datetime >= NOW() ORDER BY datetime LIMIT 2');
return $query->result();
}

In config/autoload.php, set a model to load on each page load. then call $this->db->query("SET time_zone='+0:00'"); in that model constructor.

config/autoload.php

$autoload['model'] = array('default_model');// for ex, "say default_model"

In application/models, create a new model file with name of "default_model.php" and add below code.

application/models/default_model.php

class Default_model extends CI_Model {

function __construct()
{
    // Call the Model constructor
    parent::__construct();
    $this->db->query("SET time_zone='+0:00'");
}
   }

On each page load, this constructor will be called and mysql timezone will be set to +0:00.

Add these line in your config file and then check, it is working for me

$config['time_reference'] = 'gmt';# Default should be GMT
date_default_timezone_set('UTC');# Add this line after creating timezone to GMT for reflecting

I like the solution proposed by Kumar however, I didn't need to set this globally, only when showing dates stored in UTC time in my db.

In my api model I have the following function.

  public function setDBTimeOffset(){
    $dt = new DateTime();
    $offset = $dt->format("P");
    $result = $this->db->query("SET time_zone='$offset';");
    return $result;
  } # END FUNCTION setDBTimeOffset

From my controller, I call the following first.

  $this->api->setDBTimeOffset();

Followed by the call to the function that queries the db. For example, I am fetching some user history.

  $data["viewData"]["allHistory"] = $this->api->getUserHistory("ALL", 0, 10000);

When I display the output, the dates are in my timezone. I hope this helps someone, somewhere in time (couldn't resist).

You can set it in the index.php file in your project folder on top and after <?php

<?php
date_default_timezone_set('Asia/Bangkok');
