> Key: ARROW-17425
> URL: https://issues.apache.org/jira/browse/ARROW-17425
> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Affects Versions: 9.0.0
> Reporter: SHIMA Tatsuya
> Assignee: SHIMA Tatsuya
> Priority: Major

> Since the current unit is fixed to "s", an error will occur if a time
> containing sub-seconds is given.
> {code:r}
> "1970-01-01T00:00:59.123456789" |>
> data.frame(x = _) |>
> arrow::arrow_table() |>
> dplyr::mutate(x = lubridate::as_datetime(x, tz = "UTC")) |>
> dplyr::collect()
> #> Error in `dplyr::collect()`:
> #> ! Invalid: Failed to parse string: '1970-01-01T00:00:59.123456789' as a
> scalar of type timestamp[s]
> {code}
> I thought that nanoseconds should be used, but it should be noted that
> POSIXct is currently supposed to be converted to microseconds, as shown in
> ARROW-17424.
