 // Obtain the total milliseconds

 long totalMilliseconds = System.currentTimeMillis();

 // Obtain the total seconds

 long totalSeconds = totalMilliseconds / 1000;

 // Compute the current second in the minute in the hour

 long currentSecond = totalSeconds % 60;

 // Obtain the total minutes

 long totalMinutes = totalSeconds / 60;

 // Compute the current minute in the hour

 long currentMinute = (totalMinutes % 60);

 // Obtain the total hours

 long totalHours = totalMinutes / 60;

 // Compute the current hour

 long currentHour = totalHours % 24;

 // Display results

 System.out.println("Current time is " + currentHour + ":" + currentMinute + ":" + currentSecond + "GMT");
