What is the field type?
timestamp? timestamp with time zone?
Are you using the latest java timezone updates? (tzupdater)
>As said before, since prepareThreshold=0 solved my problem
Then binaryTransferDisable=DATE,DATE_ARRAY,TIMESTAMP,TIMESTAMP_ARRAY,TIMESTAMPTZ,TIMESTAMPTZ_ARRAY,TIME,TIME_ARRAY,TIMETZ,TIMETZ_ARRAY
connection property might be better workaround.
