David Li commented on ARROW-14822:
----------------------------------
It appears pandas has a similar operation:
[https://pandas.pydata.org/docs/reference/api/pandas.Series.dt.round.html]
which also has options for handling ambiguous/nonexistent dates. Neither allow
you to control the rounding mode (and it is not specified for Pandas). Postgres
only implements truncation:

> [C++] Implement floor/ceil/round for temporal objects
