For time-based related partition transforms Iceberg makes the file partition path human readable (i.e. for a day transform we get /date=2019-01-15 even though the actual value of the partition is of type Integer, namely the diff in number of days since epoch time).
So when we rely on Iceberg to retrieve the partition from the file path we get an error - so today we need to convert its value to the Iceberg Integer equivalent (we basically re-apply the function of determining the diff in number of days since epoch time). Reading a path `protocol:/internet/date=2019-01-01` should actually translate to extracting date as 17907 (days since epoch till 2019-01-01) - assuming that `date` is a `day` function backed partition transform. Makes sense? Is it a known limitation or is it an issue? If it's an issue, do you know if it's already tracked? /Filip
