Why Does My MySQL JDBC Driver (5.1.33) Throw a Time Zone Error After Upgrading?

Time Zone Issue with MySQL 5.1.33 JDBC Driver

A user has reported an issue when upgrading from MySQL JDBC driver version 5.1.23 to 5.1.33. Specifically, after the upgrade, the application was throwing an error related to an unrecognized time zone.

Cause

The issue arises due to changes in the handling of time zones in the updated driver. In MySQL JDBC driver 5.1.33, the default time zone interpretation is more strict, and the server's time zone must be explicitly specified through the serverTimezone configuration property.

Resolution

To resolve the issue, the user should add the following parameter to the connection string:

?serverTimezone=UTC

This parameter explicitly sets the server's time zone to UTC. The resulting connection string might look like this:

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