-----------------------------------
Labels: compute kernel pull-request-available (was: compute kernel)
> [C++] Implement datediff kernel
> -------------------------------
>
> Key: ARROW-13548
> URL: https://issues.apache.org/jira/browse/ARROW-13548
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: David Li
> Assignee: David Li
> Priority: Major
> Labels: compute, kernel, pull-request-available
> Fix For: 6.0.0
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Add a kernel to compute the number of years, months, weeks, days, hours,
> minutes, (micro/milli/nano)seconds, or quarters between two timestamps.
> This should act like SQL's DATEDIFF ([SQL
> Server|https://docs.microsoft.com/en-us/sql/t-sql/functions/datediff-transact-sql?view=sql-server-ver15]).
> Pandas doesn't have a convenient equivalent except in the case of days
> (pd.Timedelta.days) but it can be [calculated using
> Timestamp.to_period|https://stackoverflow.com/questions/54171674/calculating-the-amount-of-full-months-between-two-dates].
> We have hinnant's date library vendored and this should hopefully be
> implementable with that.
