parquet-tools cat command does not consider logical type

The parquet-tools cat command doesn't format timestamps, outputting them as numbers instead.  The parquet-tools dump command does format as timestamps, so the code has been written.

Using the attached file:

$ java -jar parquet-tools-.jar cat -j datetime_utc_adjust.parquet
{"ID":1,"DT":1604297946277} 

$ java -jar parquet-tools-.jar dump datetime_utc_adjust.parquet

...

Inizia dai punti di ingresso dei comandi cat e dump di parquet-tools e riproduci il problema usando il file allegato datetime_utc_adjust.parquet. Confronta il modo in cui ciascun comando gestisce il tipo logico timestamp; il lavoro è completato quando cat -j emette il timestamp nello stesso formato di dump invece che come valore numerico.
