Please close this one. > [C++] Implement maths with timestamps > ------------------------------------- > > Key: ARROW-14947 > URL: https://issues.apache.org/jira/browse/ARROW-14947 > Project: Apache Arrow > Issue Type: Sub-task > Components: C++ > Reporter: Nicola Crane > Priority: Major > > Please could we have maths with timestamps implemented? > In order to implement some of the functionality I'd like in R, I need to be > able to do maths with dates. For example: > * Addition and subtraction: Timestamp + Duration = Timestamp (with and > without rollback so have ability to do e.g. 2021-03-30 minus 1 month and > either get a null back, or 2021-02-28), plus the ability to specify whether > to rollback to the first or last, and whether to preserve or rest the time. > See https://lubridate.tidyverse.org/reference/mplus.html for documentation of > the R functionality. > * Multiplying Durations: Duration * Numeric = Duration -- This message was sent by Atlassian Jira (v8.20.1#820001)
