### Rationale for this change In R 4.5.2+, `as.POSIXct(x = NULL)` creates a zero-length `POSIXct` with `INTSXP` (integer) type, not `REALSXP` (double). The `GetVectorType()` function in `r_to_arrow.cpp` only checked for `POSIXct` in the `REALSXP` branch, so it misclassified zero-length `POSIXct` as `INT32`. ### What changes are included in this PR? Map any `POSIXct` object to correct class by adding the check to the `INTSXP` branch of `GetVectorType()` ### Are these changes tested? Yes ### Are there any user-facing changes?
