> Avatica [serializes timestamps|https://github.com/apache/calcite-avatica/blob/9dfc5cad3efe72e9b14513b15a988ba86ab5a4ea/core/src/main/java/org/apache/calcite/avatica/remote/TypedValue.java#L447] as the integer number of milliseconds since epoch. We would like support for microsecond precision, although we only need it for {{TIMESTAMP_WITH_LOCAL_TIME_ZONE}}, which is currently lacking proper support (The recommended corresponding Java type as per [the spec|https://download.oracle.com/otn-pub/jcp/jdbc-4_2-mrel2-spec/jdbc4.2-fr-spec.pdf?AuthParam=1664936014_d36468601dd3a115d7d95c975043ff3a] is {{java.time.OffsetDateTime}}).
