Why formatted output 1900-01-01 00:05:43

Question

Date default in my database is 1900-01-01 00:00:00, but i need to format the output when the page is displayed this is my code,But the result wasn't what I wanted.

package com.niocoder;

import java.sql.Timestamp;
import java.time.LocalDateTime;
import java.time.ZoneId;
import java.time.format.DateTimeFormatter;
import java.util.Date;

/**

public class DateTest {

    private static final String DEFALUT_TIME = "1900-01-01 00:00:00";

    public static void main(String[] args) {
        String dateStr = "1900-01-01 00:00:00";
        Timestamp timestamp = Timestamp.valueOf(dateStr);
        System.out.println(ZoneId.systemDefault());
        String resultDate = getDateTimerStrByDate(new java.util.Date(timestamp.getTime()));
        resultDate = DEFALUT_TIME.equals(resultDate) ? "" : resultDate;
        System.out.println(resultDate);
    }


    public static String getDateTimerStrByDate(Date date) {
        return dateToLocalDateTime(date).format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));
    }

    public static LocalDateTime dateToLocalDateTime(Date date) {
        return date.toInstant().atZone(ZoneId.systemDefault()).toLocalDateTime();
    }
}

output : Asia/Shanghai 1900-01-01 00:05:43
