Java Data Type - 如何从基准日期，即01/01/1970获取日期时间

import java.time.LocalDateTime;
import java.time.ZoneOffset;

public class Main {
    public static void main(String[] args) {
      //Getting date from the base date i.e 01/01/1970
      LocalDateTime dateFromBase = LocalDateTime.ofEpochSecond(10000, 0, ZoneOffset.UTC);
      System.out.println("10000th second time from 01/01/1970= "+dateFromBase);
    }
}
