Deserialise new timestamp parquet format with low-level api #478

Closed elan-hwang closed 4 weeks ago

Issue description

If I write a parquet file in python using the legacy int96 timestamps: pq.write_table(tbl, path, use_deprecated_int96_timestamps=True) Then parquet.net can detect the DateTime format: image

However if I do use_deprecated_int96_timestamps=False, then the low-level api is not able to detect the type, instead it detects it as int64 type: image

So is there a way to deserialise the new timestamp format with low-level api?
