Why is my JDBC Connection Failing with \'Server Time Zone Value \'AEST\' is Unrecognized\'?

The server time zone value 'AEST' is unrecognized or represents more than one time zone

This error occurs when the server time zone (AEST in this case) is unrecognized or represents multiple time zones. To address this, you need to configure the server or JDBC driver (specifically, the serverTimezone configuration property) to use a more specific time zone value.

MySQL Specifics

For MySQL, the default serverTimezone is UTC. However, if you create a database with a specific time zone, MySQL stores tables with timestamps in a UTC-based format.

When connecting to the database, the JDBC driver tries to convert these timestamps to the time zone of your JVM. If your JVM's time zone is different from the database's time zone and you didn't specify serverTimezone, the driver may not convert the timestamps correctly, leading to this error.

Solution

To fix this issue in MySQL, specify the serverTimezone property in your connection URL or in your Hibernate configuration:

• Connection URL:

  jdbc:mysql://localhost:3306/database_name?serverTimezone=your_timezone

• Hibernate Configuration:

  <property name="hibernate.connection.server_timezone">your_timezone</property>

Where your_timezone represents the specific time zone you want to use.

Additional Tips

• If you're unsure of the correct time zone, print out the default time zone using TimeZone.getDefault().
• Check the format of the time zone value. It should follow the IANA time zone format, such as "Australia/Sydney".
• If you're still having issues, consult the documentation for the specific database and JDBC driver you're using.
