Setting timezone=UTC result in SQLSyntaxErrorException

    XMLWordPrintable

    Details

      Description

      Given a server that does not run in UTC, the new `timezone` parameter described here https://mariadb.com/kb/en/about-mariadb-connector-j/#jdbc-api-implementation-notes cannot work, even with mysql_tzinfo_to_sql fully and correctly loaded.

      In `StandardClient` UTC get's translated into a fixed offset:

      if (mustSetTimezone) {
              if (clientZoneId.getRules().isFixedOffset()) {
                ZoneOffset zoneOffset = clientZoneId.getRules().getOffset(Instant.now());
                sessionCommands.add("time_zone='" + zoneOffset.getId() + "'");
              } else {
                sessionCommands.add("time_zone='" + conf.timezone() + "'");
              }
            }
      

      Which is literal `Z` (See `System.out.println(ZoneId.of("UTC").getRules().getOffset(Instant.now()));`}

      MariaDB server cannot handle this, resulting in

      Exception in thread "main" java.sql.SQLSyntaxErrorException: (conn=2235) Setting configured timezone 'UTC' fail on server.
      Look at https://mariadb.com/kb/en/mysql_tzinfo_to_sql/ to load tz data on server, or set timezone=disable to disable setting client timezone.
