Review Comment:
   missed that part, why don't we do similar to PartFilterVisitor.java
   ````
   MetaStoreUtils.convertStringToDate((String) nodeValue);
   ````
   and use nodeValue if no exceptions;
   if that does some date with TZ string reformatting, can we create a helper 
method in MetaStoreUtils
