How to Fix the Hibernate Server Time Zone Error: \'AEST\' Unrecognized?

Server Time Zone Error: 'AEST' Unrecognized

Problem:

An unrecognized server time zone, 'AEST,' results in an error during Hibernate connection establishment.

Caused by: java.sql.SQLException: The server time zone value 'AEST' is unrecognized or represents more than one time zone.

Solution:

To resolve this error, you need to specify a more specific time zone value using the serverTimezone configuration property for the JDBC connection.

Here's how to do it:

1. Add serverTimezone to Connection String:
   In your JDBC connection URL, add the serverTimezone parameter with a specific time zone. For example, if your time zone is "Australia/Sydney," replace "AEST" with "Australia/Sydney" in your code:

jdbc:mysql://localhost:3306/parking_hib?useLegacyDatetimeCode=false&serverTimezone=Australia/Sydney;useSSL=false;

2. Disable Legacy Datetime Code:
   Ensure that you set useLegacyDatetimeCode to false in the JDBC connection URL, as this might interfere with time zone handling.
3. Update JDBC Connector:
   If you're using an outdated version of the JDBC connector, consider updating to the latest version, as it might include bug fixes related to time zone management.

Additional Troubleshooting:

• Verify Time Zone: Double-check the time zone you're using in the serverTimezone parameter. It should match the time zone of your database server.
• MySQL Server Configuration: Ensure that the time zone is correctly configured in the MySQL server. You can execute the following command to verify and potentially adjust the time zone:

SET GLOBAL time_zone = 'Australia/Sydney';

• Library Compatibility: Make sure that the version of the JDBC connector you're using is compatible with the version of MySQL you're connecting to.

Note: If you're still having issues with the time zone, consult the documentation for your specific database or JDBC connector for additional troubleshooting steps.
