I use as database server MariaDB (10.1.40-MariaDB-0ubuntu0.18.04.1 Ubuntu 18.04). Execute follow command: {code:java} mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p mysql {code} Add follow lines into the file /etc/mysql/mariadb.conf.d/50-server.cnf: {code:java} [mysqld] ... # Timezone default_time_zone=Europe/Berlin ... {code} Don't forget to adjust the timezone for your environment. After an restart of the database service (in my case mariadb), the error had be gone. was (Author: whitemoon): After some tests i found a solution that works for me.

You must configure either > the server or JDBC driver (via the serverTimezone configuration property)..... > loading the timezone table and setting it globally on the mariadb resolved > this, however it might be beneficial to add a system property that will set > within the connection string. -- This message was sent by Atlassian JIRA (v7.6.14#76016)
