Review comment:
Oh, there is a parsing chain in CSV. It used to be "DoubleType ->
TimestampType" and now it is "DoubleType -> TimestampNTZType -> TimestampType".
This is the order in which we infer columns. So if we cannot parse the
timestamp as TIMESTAMP_NTZ, we will try parsing it as a timestamp with
timezone. Does it answer your question?
