Original description in ARROW-11090:
"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.)"

For example, in R, lubridate has the following functionality:

• rollbackward() or rollback() which changes a date to the last day of the previous month or to the first day of the current month

• rollforward() which rolls to the last day of the current month or to the first day of the next month.

• all of the above also offer the option to preserve hms (hours, minutes and seconds) when rolling.

  This functionality underpins functions such as %m-% and %m+% which are used to add or subtract months to a date without exceeding the last day of the new month.
