-------------------------------------

             Summary: Spark  - Truncate date by Day / Hour
                 Key: SPARK-22478
                 URL: https://issues.apache.org/jira/browse/SPARK-22478
             Project: Spark
          Issue Type: New Feature
          Components: Spark Core
    Affects Versions: 2.2.0
            Reporter: david hodeffi
            Priority: Trivial


Currently it is possible to truncate date/timestamp only by month or year,
There is a missing functionality to truncate by hour/day.
A usecase that requires this functionality is: Aggregating financial transaction of a party in order to create daily/hour summary. 
Those summaries are required for machine learning algorithms.
