Question

I have a number of seconds. Let\'s say 270921. How can I display that number saying it is xx days, yy hours, zz minutes, ww seconds?

Answer 1

I modified the answer given by @Mike to add dynamic formatting based on the size of the result

      def formatted_duration(total_seconds)
        dhms = [60, 60, 24].reduce([total_seconds]) { |m,o| m.unshift(m.shift.divmod(o)).flatten }

        return "%d days %d hours %d minutes %d seconds" % dhms unless dhms[0].zero?
        return "%d hours %d minutes %d seconds" % dhms[1..3] unless dhms[1].zero?
        return "%d minutes %d seconds" % dhms[2..3] unless dhms[2].zero?
        "%d seconds" % dhms[3]
      end
