Romain François commented on ARROW-3702:
----------------------------------------
it's currently timestamp.
{code:r}
arrow::array(Sys.time())$type
#> arrow::Timestamp
#> timestamp[us, tz=GMT]
{code}

> [R] POSIXct mapped to DateType not TimestampType?
> -------------------------------------------------

> Key: ARROW-3702
> URL: https://issues.apache.org/jira/browse/ARROW-3702
> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Reporter: Javier Luraschi
> Priority: Major
> Fix For: 0.14.0

> Why was POSIXct mapped to
> [DataType|https://arrow.apache.org/docs/cpp/classarrow_1_1_date_type.html#a6aea1fcfd9f998e8fa50f5ae62dbd7e6]
> not
> [TimestampType|https://arrow.apache.org/docs/cpp/classarrow_1_1_timestamp_type.html#a88e0ba47b82571b3fc3798b6c099499b]?
> What are the PRO/CONs from each approach?
> This is mostly to interoperate with Spark which choose to map POSIXct to
> Timestamps since in Spark, not Arrow, dates do not have a time component.
> There is a way to make this work in Spark with POSIXct mapped to DateType by
> mapping DateType to timestamps, so mostly looking to understand tradeoffs.
> One particular question, timestamps in arrow seem to support timezones,
> wouldn't it make more sense to map POSIXct to timestamps?
