> {{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 because it internally calls array_sort_indices
> 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}
