MySQL Connector Error "The Server Time Zone Value Central European Time" During Java Database Connection

This issue arises when establishing a database connection using the MySQL connector in Java. The error message indicates that the server time zone value provided, "Central European Time," is not recognized or represents multiple time zones. To resolve this issue, the server time zone value must be specified explicitly using the serverTimezone configuration property.

One common solution is to specify the specific time zone using the Java TimeZone class. The following code demonstrates how to set the time zone to Europe/Amsterdam:

TimeZone timeZone = TimeZone.getTimeZone("Europe/Amsterdam");
connection = DriverManager.getConnection(jdbcUrl, user, password);
connection.setServerTimeZone(timeZone);

Another approach, as indicated by the user, is to configure the time zone directly in the connection URL. The following example sets the time zone to Europe/Amsterdam:

jdbc:mysql://127.0.0.1:3306/rk_tu_lager?useLegacyDatetimeCode=false&serverTimezone=Europe/Amsterdam&useSSL=false

By specifying the time zone explicitly, the MySQL connector can accurately interpret and process datetime values, ensuring correct time-related functionality in the Java application.
