Description

The following works on macOS

library(arrow, warn.conflicts = FALSE)

a <- Array$create("2021 September 13")
call_function("strptime", a, options = list(format = "%Y %B %d", unit = 0L))
#> Array
#> <timestamp[s]>
#> [
#>   2021-09-13 00:00:00
#> ]

but fails on Windows, with:

#> Error: Invalid: Failed to parse string: '2021 September 13' as a scalar of type timestamp[s]

I came across this while implementing the parse_date_time() bindings, when the Windows CI jobs were failing to parse date with the months expressed either as name or short name. https://github.com/apache/arrow/runs/6270529412?check_suite_focus=true#step:20:20856
