> Arrow's 'Time' definition is below:
> {code:java}
> { "name" : "time", "unit" : "SECOND|MILLISECOND|MICROSECOND|NANOSECOND", "bitWidth": /* integer: 32 or 64 */ }{code}
> [http://arrow.apache.org/docs/metadata.html]
>  
> But Parquet only supports 'TIME_MILLIS' and 'TIME_MICROS'.
>  [https://github.com/Apache/parquet-format/blob/master/LogicalTypes.md]
> Therefore SchemaConverter should not convert from TimeUnit.SECOND AND TimeUnit.NANOSECOND of Arrow to Parquet.
