             Summary: [C++] Fix sort_indices, array_sort_indices timestamp support discrepancy
                 Key: ARROW-12087
                 URL: https://issues.apache.org/jira/browse/ARROW-12087
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
            Reporter: Ian Cook


{{sort_indices}} supports sorting by timestamp arrays, but {{array_sort_indices}} does not. Here's some example R code to demonstrate this (but this example code depends on ARROW-11703 to run):
{code:java}
tbl <- tibble::tibble(
  dttm = lubridate::ymd_hms(c("2021-01-01 00:00:00", "1900-01-01 00:00:00")),
)
rb <- arrow::record_batch(tbl)

# this fails:
arrow:::call_function(
  "array_sort_indices",
  rb$dttm,
  options = list(order = F)
)
## Error: NotImplemented: Function array_sort_indices has no kernel matching input types (array[timestamp[us, tz=UTC]])

# this fails
arrow:::call_function(
  "sort_indices",
  rb,
  options = list(names = "dttm", orders = 0L)
)
## Error: NotImplemented: Function array_sort_indices has no kernel matching input types (array[timestamp[us, tz=UTC]])

# this succeeds
arrow:::call_function(
  "sort_indices",
  rb,
  options = list(names = c("dttm", "dttm"), orders = 0L)
) 
## Array
## <uint64>
## [
##   1,
##   0
## ]{code}
