Hi, Last december we shared a timestamp harmonization proposal <https://goo.gl/VV88c5> with the Hive, Spark and Impala communities. This was followed by an extensive discussion in January that lead to various updates and improvements to the proposal, as well as the creation of a new document for file format components. February has been quiet regarding this topic and the latest revision of the proposal has been steady in the recent weeks.
In short, the following is being proposed (please see the document for details): - The TIMESTAMP WITHOUT TIME ZONE type should have LocalDateTime semantics. - The TIMESTAMP WITH LOCAL TIME ZONE type should have Instant semantics. - The TIMESTAMP WITH TIME ZONE type should have OffsetDateTime semantics. This proposal is in accordance with the SQL standard and many major DB engines. Based on the feedback we got I believe that the latest revision of the proposal addresses the needs of all affected components, therefore I would like to move forward and create JIRA-s and/or roadmap documentation pages for the desired semantics of the different SQL types according to the proposal. Please let me know if you have any remaning concerns about the proposal or about the course of action outlined above. Thanks, Zoltan
