   The arrow-rs kernel appears to support casting to/from timestamp without 
timezone (timezone is `None`):
   
   
https://github.com/apache/arrow-rs/blob/1d0abfafe0da7c28b562fa0ba8c65a10b65a0821/arrow-cast/src/cast.rs#L257-L265
   
   my reading of the code is that if the timestamp has a timezone the arrow 
kernel will fail (can not cast types)
