Created attachment 145172 [details] When i click test or testing button in auth of db, it appears that message. In LibreOffice Base (version 6.1.1.2 (x64)), when i select MySQL as db existent and JDBC as connection of db, there should be 2 options to fix Time Zone problem and should be added in creation of database: useLegacyDatetimeCode (boolean, if false, it will use serverTimeZone, if not, it wont) and serverTimezone (string and should be exist a list of Time Zones, like Europe/London).
Let's put this one to UNCONFIRMED for the moment.
