Description

December 27th to 31st 2020 gets converted into 2021 while trying to use 

`DateFormatUtils.format` method. 

import org.apache.commons.lang3.time.DateFormatUtils;
import org.apache.commons.lang3.time.DateUtils;

public class DateEx {

    public static void main(String... args) throws Exception{

        String startDateStr = "2020-12-31";


        String startDate = DateFormatUtils
                .format(DateUtils.parseDate(startDateStr, "YYYY-MM-dd"), "YYYY-MM-dd-HH.MM.SS.mmmmmm");
        System.out.println("startDate with Timestamp - " + startDate);

    }
}

 

Actual Output -  2021-12-31-00.12.00.000000

Expected Output - 2020-12-31-00.12.00.000000

 

Can someone look into it.
