[Java] JDBC test failures for Windows build with timezone != UTC

Run "mvn install" in the java directory on a system with timezone set to PST (Pacific Standard, 8 hours behind UTC).

For the arrow-jdbc module, the following errors occur:

**Environment**: Windows 10, Java 8

Führe "mvn install" aus dem java-Verzeichnis unter Windows 10 mit der auf PST eingestellten Zeitzone aus und untersuche anschließend die fehlschlagenden arrow-jdbc-Tests: JdbcToArrowDataTypesTest, JdbcToArrowNullTest, JdbcToArrowTest und JdbcToArrowVectorIteratorTest. Als erledigt gilt die Aufgabe, wenn die sieben gemeldeten zeitzonenabhängigen Fehler nicht mehr auftreten und die Tests des Moduls erfolgreich sind.
