Dragoș Moldovan-Grünfeld commented on ARROW-11090:
--------------------------------------------------
[~rokm] [~jonkeane] described it in the description for this very ticket:
"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.)"
Are more details needed or do you think this is clear enough?
