**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** `arrow-json` needs to use RFC3339 style timestamps for timestamps with timezones as already done in `arrow-csv`. We intend to fix the upstream InfluxDB IOX bug https://github.com/influxdata/influxdb_iox/issues/2095. **Describe the solution you'd like** The [`array_value_to_string`](https://github.com/apache/arrow-rs/blob/master/arrow-cast/src/display.rs#L311) function (from `arrow-cast`) already supports RFC3339 style timestamps. We would use this function inside `arrow-json` to change to writing RFC3339 style timestamps while writing out record batches to JSON files. The `array_value_to_string` function will be modified a bit to print a trailing `Z`, when the timestamp is in UTC. **Describe alternatives you've considered** We could also implement a [handle_timestamp](https://github.com/apache/arrow-rs/blob/master/arrow-csv/src/writer.rs#L242) helper function as present in `arrow-csv` inside `arrow-json`, but that would be a duplication of code. **Additional context** We intend to use `array_value_to_string` across `arrow-csv`, `arrow-json`, and `arrow-pretty` for consistency in the RFC3339 timestamp implementation in the near future. -- This is an automated message from the Apache Git Service.
