> Looks like the json writer.rs code in arrow doesn't support writing out
> timestamps. When I tried to write out a `TimestampNanosecondArray` I got the
> following error:
> ```
> thread 'influxdb_ioxd::http::tests::test_query_json' panicked at 'Unsupported
> datatype: Timestamp(
> Nanosecond,
> None,
> )',
> /Users/alamb/.cargo/git/checkouts/arrow-3a9cfebb6b7b2bdc/3e825a7/rust/arrow/src/json/writer.rs:326:13
