Re: [I] [Spark, PyIceberg] Different behavior in downcasting ns [iceberg]

URL: https://github.com/apache/iceberg/issues/13679#issuecomment-3166132355
Hi, I'm seeing issues when reading Parquet files with timestamp[ns]. PyIceberg downcasts to us, but Spark misinterprets the values and shows timestamps far in the future.
Is there a recommended way to handle timestamp[ns] with Iceberg? Would normalizing to us before writing be the best option, or is there a better approach?
Thanks!
