Try setting the locale in PHP for the current application in code.

1. run in MYSQL : SELECT @@system_time_zone;
2. Add this to the first line in PHP code, date_default_timezone_set(‘US/Eastern’);
3. Replace ‘US/Eastern’ in Step 2, with the timezone value you got from Step 1.
4. In codeigniter, you can place Step 2 line in config.php
5. If there are errors, use the right timezones here:
   1. https://www.php.net/manual/en/timezones.america.php
   2. date_default_timezone_set(‘America/New_York’); used for aspa and webhooks.

function getCurrentDatabaseTime() {
    $ci =& get_instance();

	$query = $ci->db->query('SELECT NOW() as `current_time`;');
    // if exist
    $results = array();
    if ($query->num_rows() > 0) {
        foreach ($query->result_array() as $row)
            {
                return $row;
            }            
    }
        
    return FALSE; 	
}
