Erro na conexão com MySQL

Esse codigo esta me retornando a seguinte Exception e eu não sei como resolver de uma forma que eu não precise alterar o código:

Wed Jun 06 00:22:36 BRT 2018 WARN: Establishing SSL connection without server’s identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn’t set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to ‘false’. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.
Exception in thread “main” java.sql.SQLException: The server time zone value ‘Hora oficial do Brasil’ is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public static void main(String[] args) throws Exception {


	String url = "jdbc:mysql://localhost:3306/projeto";

	Connection conexao = DriverManager.getConnection(url,login,senha);
