I'm implementing a count-down using Joda Time. I only need a display accuracy of seconds.

However when printing the time, the seconds are displayed as full seconds, so when the count down reaches, for example, 900ms, then "0" seconds is printed, but as a count-down it would make more sense to display "1" second, until the time actually reaches 0ms.

Example:

void printDuration(Duration d) {
  System.out.println(
    d.toPeriod(PeriodType.time()).toString(
      new PeriodFormatterBuilder().printZeroAlways().appendSeconds().toFormatter()
    )
  );
}

printDuration(new Duration(5000)); // Prints "5" => OK
printDuration(new Duration(4900)); // Prints "4" => need "5"
printDuration(new Duration(1000)); // Prints "1" => OK
printDuration(new Duration(900));  // Prints "0" => need "1"
printDuration(new Duration(0));    // Prints "0" => OK

Basically I need to the seconds to be display rounded up from milliseconds and not rounded down. Is there a way to achieve this with Joda without needing to write my own formatter?
