How does MySQL determine the time zone settings, and does it rely on PHP settings?

MySQL determines the time zone settings based on the system time zone set on the server where it is running. It does not rely on PHP settings for determining the time zone. To ensure that MySQL is using the correct time zone, you can set the time zone explicitly in your MySQL connection or configuration settings. 

// Set the time zone for MySQL connection
$mysqli = new mysqli("localhost", "username", "password", "database");
$mysqli->query("SET time_zone = '+00:00'");
