| type(parquet_reader), | intent(in) | :: | reader |
open reader. |

| character(len=*), | intent(in) | :: | name |
time/timestamp column name. |

| integer, | intent(out), | optional | :: | unit |
stored unit (a parquet_unit_* selector). |
|
| character(len=:), | intent(out), | optional, | allocatable | :: | timezone |
IANA tz, or "" if naive. |
Returns column name's stored time unit and (for a timestamp) timezone. unit
(optional) receives one of the parquet_unit_* selectors; timezone (optional,
allocatable) receives the IANA timezone string ("" for a timezone-naive timestamp or
a time column). Aborts if name is not a time/timestamp column. Distinct from
parquet_get_metadata, which serves user-defined key/value metadata rather than this
schema-level property.
