Dewey Dunnington commented on ARROW-13087:
------------------------------------------

Reprex:

{code:R}
library(arrow, warn.conflicts = FALSE)

tf <- tempfile()
write_parquet(
  data.frame(a = as.POSIXct(c("1000-01-01", "2000-01-01"))),
  tf,
  use_deprecated_int96_timestamps = TRUE, version = "1.0"
)

props <- ParquetArrowReaderProperties$create()
props$set_coerce_int96_timestamp_unit(TimeUnit$MICRO)
#> Error in eval(expr, envir, enclos): attempt to apply non-function

read_parquet(tf, props = props, as_data_frame = FALSE)
#> Table
#> 2 rows x 1 columns
#> $a <timestamp[ns]>
#> 
#> See $metadata for additional Schema metadata
