how to convert 270921sec into days + hours + minut

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

Rails has an helper which converts distance of time in words. You can look its implementation: distance_of_time_in_words

Answer 2

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

Answer 3

I just start writing ruby. i guess this is only for 1.9.3

def dateBeautify(t)

    cute_date=Array.new
    tables=[ ["day", 24*60*60], ["hour", 60*60], ["minute", 60], ["sec", 1] ]

    tables.each do |unit, value|
        o = t.divmod(value)
        p_unit = o[0] > 1 ? unit.pluralize : unit
        cute_date.push("#{o[0]} #{unit}") unless o[0] == 0
        t = o[1]
    end
    return cute_date.join(', ')

end

Answer 4

It can be done pretty concisely using divmod:

t = 270921
mm, ss = t.divmod(60)            #=> [4515, 21]
hh, mm = mm.divmod(60)           #=> [75, 15]
dd, hh = hh.divmod(24)           #=> [3, 3]
puts "%d days, %d hours, %d minutes and %d seconds" % [dd, hh, mm, ss]
#=> 3 days, 3 hours, 15 minutes and 21 seconds

You could probably DRY it further by getting creative with collect, or maybe inject, but when the core logic is three lines it may be overkill.

Answer 5

Needed a break. Golfed this up:

s = 270921
dhms = [60,60,24].reduce([s]) { |m,o| m.unshift(m.shift.divmod(o)).flatten }
# => [3, 3, 15, 21]

Answer 6

You can use the simplest method I found for this problem:

  def formatted_duration total_seconds
    hours = total_seconds / (60 * 60)
    minutes = (total_seconds / 60) % 60
    seconds = total_seconds % 60
    "#{ hours } h #{ minutes } m #{ seconds } s"
  end

You can always adjust returned value to your needs.

2.2.2 :062 > formatted_duration 3661
 => "1 h 1 m 1 s"
