Why Does MySQL JDBC Driver 5.1.33 Throw a 'Server Timezone' Error, and How Can I Fix It?

MySQL JDBC Driver 5.1.33: Addressing Time Zone Discrepancies

A common issue encountered after upgrading to MySQL JDBC driver 5.1.33 is an error message indicating an unrecognized server timezone value ('UTC'). This occurs when the JDBC driver's timezone support is utilized and the server's timezone value is not sufficiently specified.

The Cause

The root cause of this issue lies in the default timezone handling of MySQL JDBC driver 5.1.33. It expects the server timezone to be explicitly defined, whereas previous versions of the driver assumed a default timezone. This change was introduced to enhance timezone support but requires additional configuration when using UTC timezone.

The Solution

To resolve this issue and connect successfully with MySQL JDBC driver 5.1.33 using UTC timezone, the serverTimezone parameter must be explicitly specified in the connection string. This parameter informs the JDBC driver about the timezone of the database server, ensuring that the correct offset is applied to timestamps and dates.

In a Java application, this parameter can be added to the connection string as follows:

jdbc:mysql://localhost/db?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC

By specifying the serverTimezone parameter as UTC, the JDBC driver will correctly handle time zone conversions and communication with the MySQL database using the UTC timezone.
