Description

I get an error trying to write a tibble of POSIXlt data to a file. The error is a bit misleading as it refers to the column being of length 0.

posixlt_data <- tibble::tibble(x = as.POSIXlt(Sys.time()))
write_csv_arrow(posixlt_data, "posixlt_data.csv")

Error: Invalid: Unsupported Type:POSIXlt of length 0

Table
2 rows x 2 columns
$x <POSIXlt of length 0>
$y <int32>
