   Parquet has a proper Timestamp field, correct? 
https://learn.microsoft.com/en-us/common-data-model/sdk/parquet-to-cdm-datatype
   
   And that datatype supports a `precision` field which specifies 
millis/micros/nanos?
   
   So I presume this error only happens when reading an `INT` field and 
casting? If so, I'd 100% be on board copying the behavior of these other well 
known databases. Folks who stored their data properly as `Timestamp`s shouldn't 
be affected. It would be a breaking change to those who just stored as an 
`INT`, but I think now is the time to make that change since datetime support 
is relatively new... it will only get harder to change going forward.
