Weston Pace created ARROW-15537:
-----------------------------------
Summary: [C++] Decide how we want to handle time zone strings in
Substrait
Key: ARROW-15537
URL: https://issues.apache.org/jira/browse/ARROW-15537
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Weston Pace
Substrait timestamp_with_tz type does not include the timezone string as a type
parameter. This may not be an issue. Substrait functions that care about the
timezone of a column (e.g. strftime) will include the time zone string as an
argument. So for purely consumption purposes we shouldn't have any Substrait
function / operation that depends on this timezone metadata.
However, it may be an issue for export. I'm creating this JIRA as a
placeholder for someone to think the problem through more fully and decide if
we need to do anything.
