问题
I searched many links but so far I coudn`t find a solution to my problem.
I have a web hosting on Go Daddy, and it is returning different times for PHP and MySQL:
- PHP Datetime =>13/02/2018 17:10:50
- MySQL Datetime =>13/02/2018 12:10:50
I've already set my PHP timezone to:
date_default_timezone_set('America/Sao_Paulo');
Would anyone know a way to adjust the MySQL time?
Thanks

I found my solution at this link:
https://www.sitepoint.com/synchronize-php-mysql-timezone-configuration/
Actually, I synchronized my PHP and MySQL timezones. Here's the code:
define('TIMEZONE', 'America/Sao_Paulo');
date_default_timezone_set(TIMEZONE);
$now = new DateTime();
$mins = $now->getOffset() / 60;
$sgn = ($mins < 0 ? -1 : 1);
$mins = abs($mins);
$hrs = floor($mins / 60);
$mins -= $hrs * 60;
$offset = sprintf('%+d:%02d', $hrs*$sgn, $mins);
// I already have a connection function
$return = pdo_mysql("SET time_zone='$offset';");

This is because the MySQL doesn't store timezone information on DATETIME type.
Probably your PHP script is sending a ISO8601 date string with the UTC+Timezone, so MySQL ignores the Timezone and stores only the UTC.
To avoid this, you can use the TIMESTAMP type that keeps track of the timezone.
