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

Output

Nanoseconds = 050000000
Seconds since epoch = 1543241478
Milliseconds since epoch = 1543241478050
