System.out.printf("Seconds since epoch = %ts", d);

The above would display seconds since.

import java.util.Date;
public class Demo {
   public static void main(String[] args) {
      Date d = new Date();
      System.out.printf("Nanoseconds = %tN
", d);       System.out.printf("Seconds since epoch = %ts", d);    } }


Nanoseconds = 364000000
Seconds since epoch = 1543241402
