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

Weston Pace created ARROW-14111:
-----------------------------------

             Summary: [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
            Reporter: Weston Pace


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.
