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

             Summary: Fix the handling of timestamp in DataStream.from_collection
                 Key: FLINK-20457
                 URL: https://issues.apache.org/jira/browse/FLINK-20457
             Project: Flink
          Issue Type: Bug
          Components: API / Python
    Affects Versions: 1.12.0
            Reporter: Dian Fu
             Fix For: 1.13.0, 1.12.1


Currently, DataStream.from_collection firstly converts date/time/dateTime objects to int at Python side and then construct the corresponding Date/Time/Timestamp object at Java side. It will lose the timezone information. Pickle could handle date/time/datetime properly and the conversion could be avoided.
