The code to write a dat64 column (which corresponds to a RecorObject::TIME8 column) needs to include whatever conversion is necessary between the GPS times used by default internal to SlideRule and the time format/epoch used by GeoParquet.

The GeoParquet files now include a timestamp index (datetime in pandas, datetime64[ns] in numpy). This is automatically keyed off of the TIME8 RecordObject field type.
