Description

IcebergScanNode interprets the timestamp literals as UTC timestamps:
https://github.com/apache/impala/blob/b03d18863b31f0f3e66e9fa1f84cc9d625ecce29/fe/src/main/java/org/apache/impala/planner/IcebergScanNode.java#L197

It can be confusing for users, probably we should interpret them based on the local timezone.

We might need to update KuduScanNode as well:
