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, , and 00) and the strptime parser (which should add support for %z).

[jira] [Created] (ARROW-13347) [C++][Compute] Add option to return null values for nonexistent and ambiguous times

Summary: [C++][Compute] Add option to return null values for
nonexistent and ambiguous times
Key: ARROW-13347
URL: https://issues.apache.org/jira/browse/ARROW-13347
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Rok Mihevc
ARROW-13033 Implements TzLocalize kernel and can handle ambiguous and
nonexistent times by raising or shifting backwards or forwards to first valid
local time.
However we might want to be able to return null in these cases.
We could implement new flags to do so:
{{compute::TemporalLocalizationOptions::Nonexistent::NONEXISTENT_IGNORE}} and
{{compute::TemporalLocalizationOptions::Ambiguous::AMBIGUOUS_IGNORE}}
