Time difference between PHP and MySQL [duplicate]

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.
