Connecting to MySQL in Netbeans

[bla bla bla]

I downloaded and ınstalled mysql server 8.0 and ı want to use it in netbeans. When I try to connect mysql by using j connector, ı encounter an error. It's message is
"Cannot establish a connection to jdbc:mysql://localhost:3306/mysql?zeroDateTimeBehavior=convertToNull using com.mysql.jdbc.Driver (The server time zone value 'T�rkiye Standart Saati' 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 zon"

I could not copy all of the message because it was too long.I downloaded timezone_2019b_posix_sql but ı couldn't install it. How can I solve this problem
