Description

At present there are (at least) 2 possible directions:

• support an origin option in the C++ code - ARROW-15798
• support it only in the R code (once we can do arithmetic with dates and durations) - ARROW-14947 or ARROW-11090

Issue Links

• depends upon: ARROW-15098 [R] Add binding for lubridate::duration() and/or as.difftime()
• depends upon: ARROW-11090 [C++] Support temporal arithmetic ({time,date}{32,64}, timestamp, interval)
• depends upon: ARROW-15798 [R][C++] Discussion: Plans for date casting from int to support an origin option?
• is fixed by: ARROW-15800 [R] Implement bindings for lubridate::as_date() and lubridate::as_datetime()
