> [It appears that only subtract on two timestamps is currently
> supported|https://github.com/apache/arrow/commit/dd94a5809b56b32fe2fb538f688bf568d9642e3b]
> when there is more supported, we should include support for that in R.
>
> This should also cover the ability to do with and without rollback (so have
> the 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.)
