   I am not sure I understand the issue here.
   
   Iceberg defines Timestamp as microseconds from epoch. When we actually store it in files it is up to that file format to define how that type is serialized. In this case of Parquet, this is also defined as an Int64.
   
   If Presto has a bug decoding this that is indicative of a far deeper issue with the Presto read code for parquet files. 
   
   I'm also unsure how changing the underlying representation would help since it's up to the reader to decide how to display the value to users since native parquet files are not readable by humans (at least not me)
