icexelloss commented on issue #1330: wip: ARROW-1816: [Java] Resolve new vector 
classes structure for timestamp, date and maybe interval        
URL: https://github.com/apache/arrow/pull/1330#issuecomment-346236125
 
 
   @BryanCutler I am a bit reluctant to check `unit` and `timezone` if value 
holders because of performance reasons. This is currently not checked with 
other type with type params either, such as decimal. We should maybe visit this 
problem as a whole as follow up?
