    Description

      While working on https://issues.apache.org/jira/browse/ARROW-12267 , adding support for writing Timestamp types, I noticed we were also lacking support for other time types. Specifically, if you try to write an array with any of the following types as JSON it will panic:

      An example of adding support for timestamps is on https://github.com/apache/arrow/pull/9968

      ```
      pub type Date32Array = PrimitiveArray<Date32Type>;
      pub type Date64Array = PrimitiveArray<Date64Type>;
      pub type Time32SecondArray = PrimitiveArray<Time32SecondType>;
      pub type Time32MillisecondArray = PrimitiveArray<Time32MillisecondType>;
      pub type Time64MicrosecondArray = PrimitiveArray<Time64MicrosecondType>;
      pub type Time64NanosecondArray = PrimitiveArray<Time64NanosecondType>;
      pub type IntervalYearMonthArray = PrimitiveArray<IntervalYearMonthType>;
      pub type IntervalDayTimeArray = PrimitiveArray<IntervalDayTimeType>;
      pub type DurationSecondArray = PrimitiveArray<DurationSecondType>;
      pub type DurationMillisecondArray = PrimitiveArray<DurationMillisecondType>;
      pub type DurationMicrosecondArray = PrimitiveArray<DurationMicrosecondType>;
      pub type DurationNanosecondArray = PrimitiveArray<DurationNanosecondType>;
      ```
