> Key: ARROW-13549
> URL: https://issues.apache.org/jira/browse/ARROW-13549
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: David Li
> Assignee: David Li
> Priority: Major
> Labels: kernel, pull-request-available
> Fix For: 6.0.0
>
> Time Spent: 3h 50m
> Remaining Estimate: 0h
>
> Add a kernel that can extract just the date or the time from a timestamp.
> This should behave like Postgres DATE/CAST(... as TIME), or Pandas
> Timestamp.date/Timestamp.time.
> Extracting the date appears to be doable with an unsafe cast, but it might be
> more convenient to have an explicit kernel (and an unsafe cast, at least in
> the Python bindings, disables all checks, not just the check we care about).
