Question

I am newbie in Java. I am trying to convert epoch time human format time. I refereed many web site, every one mentioned below steps but I am getting wrong output.

String format = "dd/MM/yyyy HH:mm:ss";
DateFormat dateFormat = new SimpleDateFormat(format);
String expDate=dateFormat.format(new Date(1478017281));
System.out.println(expDate);

System Output :

Expected Output:

The Date constructor takes a long argument which is supposed to be the time in milliseconds, not seconds. Add 3 0's at the end of it and it will print the expected result.
