[jira] [Comment Edited] (SPARK-8864) Date/time function and data
type design
[ https://issues.apache.org/jira/browse/SPARK-8864?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14616293#comment-14616293 ]

------------------------------------------------------------
Then we are using a Long for us. Long can be up to 9.2E18, which is more than 1E8 days. Hive is using a Long for seconds and an int for nanoseconds, but I think a single Long here for day-time interval is fine.
