[jira] [Commented] (SPARK-8186) date/time function: date_add

    [ https://issues.apache.org/jira/browse/SPARK-8186?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16198630#comment-16198630 ] 

eugen yushin commented on SPARK-8186:
-------------------------------------

Unfortunately, current implementation doesn't correspond to provided specification. `date_add` always returns DateType (and truncate time part of timestamp value).
