-----------------------------------
Summary: [C++] Allow timestamp parser to parse offset strings
Key: ARROW-13348
URL: https://issues.apache.org/jira/browse/ARROW-13348
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Weston Pace
Neither the ISO8601 parser nor the strptime parser support parsing timezone
offset strings (e.g. {{2017-08-19 12:22:11.802755+00}}). These are sometimes
emitted by other tools (e.g. Postgresql) and should be supported for
compatibility. I think it's acceptable for them to parse to Timestamp(units,
"UTC") or Timestamp(units, offset) whichever is more convenient.
This issue doesn't necessarily require supporting tzdata timezone names (e.g.
"America/Denver", etc.) and those technically aren't ISO8601 compliant anyways.
Support should be added to both the ISO-8601 parser (which should support
00:00, 0000, and 00) and the strptime parser (which should add support for %z).
