-------------------------------------
For example, currently {color:#4c9aff}datetime.datetime (2013, 12, 5, 0, 3, 13,
122000, tzinfo = timezone('Asia/Chongqing'){color}) will be converted to
{color:#4c9aff}1386172633122000{color} and sent to the java side. My task is
use Pickle package the {color:#4c9aff}datetime{color}
{color:#4c9aff}object{color} and sent to the java side, finally used to
construct a {color:#4c9aff}java.sql.Timestamp{color} object.
Is my understanding correct?[~dian.fu]

> Project: Flink
> Issue Type: Bug
> Components: API / Python
> Affects Versions: 1.12.0
> Reporter: Dian Fu

> Priority: Major
> 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.
