POSTMAN 正在返回值更改的日期字段

I am consuming a REST service and I am receiving a JSON with date attributes that do not match what is in my database. I have two fields called "initialDate" and "finalDate". In the database they are like this:

07/MAR/19 00:00:00
07/SEP/19 23:59:59

The database timezone:

select dbtimezone from dual;
+00:00

In my object, inside the Java class, the content of the attributes comes as:

public class Klass {

 @NotNull
 private Date initialDate; //initialDate.toString() "Thu Mar 07 00:00:00 CLT 2019"

 @NotNull
 private Date finalDate; // finalDate.toString() "Sat Sep 07 23:59:59:9 CLT 2019"

 public Date initialDate() {
    return this.initialDate == null ? null : new Date(initialDate.getTime());
 }

 public void setInitialDate() {
     this.initialDate = initialDate == null ? null : new Date(initialDate.getTime());
 }

 public Date finalDate() {
    return this.finalDate == null ? null : new Date(finalDate.getTime());
 }

 public void setFinalDate() {
    this.finalDate = finalDate == null ? null : new Date(finalDate.getTime());
 }

}

However, in my POSTMAN, it returns this:

initialDate: "2019-03-07T03:00:00Z",
finalDate: "2019-09-08T02:59:59Z"

Why is POSTMAN adding these 3 hours to my service response? I already try to change the timezone of Windows, but there's no difference.

解决方案

After some research, I've found this article that send me to a solution.

Date format Mapping to JSON Jackson

According by the write-up, In my custom class, I set the following attributes:

DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSSZ");
df.setTimeZone(TimeZone.getDefault());
this.setDateFormat(df)

In this ways, I get the result as I'd like:

{
  "initialDate" : "2019-03-07T00:00:00.000-0300",
  "finalDate" : "2019-09-07T23:59:59.000-0300"
}
