`java.sql.Timestamp` (used by Tempto and Presto JDBC connectors), Joda Time and Java Time differ in their time zone offset information for historic dates. We cannot guarantee correct results for these dates. See 42c3375 for a similar change for date values.
The existing `timestamp` handling was not correct, regardless of timestamp semantics. This commit introduces - as good as possible timestamp handling that is guaranteed to work (using `java.sql.Timestamp`) - timestamp handling that can work, if only driver supports `LocalDateTime` - tests for PostgreSQL
