[jira] [Updated] (ARROW-14111) [C++] Add extraction function support for time32/time64

     [ https://issues.apache.org/jira/browse/ARROW-14111?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Weston Pace updated ARROW-14111:
--------------------------------
    Component/s: C++

> [C++] Add extraction function support for time32/time64
> -------------------------------------------------------
>
>                 Key: ARROW-14111
>                 URL: https://issues.apache.org/jira/browse/ARROW-14111
>             Project: Apache Arrow
>          Issue Type: Improvement
>          Components: C++
>            Reporter: Weston Pace
>            Priority: Major
>
> time64('ns') should support:
>  - hour
>  - minute
>  - second
>  - millisecond
>  - microsecond
>  - nanosecond
>  - subsecond
> time64('us'), time32('ms'), and time32('s') should support those values that fit their resolution.
> It's probably debatable if something like millisecond(time32('s')) should be supported but for ease of use it would probably be simplest to just hard code these to return 0.
