@joshuapinter, nice code, but I'm not the Magne that contributed it to SO.

Nice! I also needed days, so thanks @alexwebgr
Just a small change, in case it's more than 48 hours

def formatted_duration(total_seconds)
    days = total_seconds / (60 * 60 * 24)
    hours = total_seconds / (60 * 60)
    hours -= (24 * days) if days >= 1
    minutes = (total_seconds / 60) % 60
    seconds = total_seconds % 60

    "#{days}d #{hours}h #{minutes}min #{seconds}s"
end

You can also use %T, it's a combination shortcut to get 24-hour time (%H:%M:%S)

Time.at(624).gmtime.strftime('%T')
=> "00:10:24"

  def formatted_duration(total_seconds)
    days = (total_seconds / (60 * 60 * 24)).to_i
    hours = ((total_seconds / (60 * 60)) % 60).to_i
    minutes = ((total_seconds / 60) % 60).to_i
    seconds = (total_seconds % 60).to_i

    "#{days} d. #{hours} h. #{minutes} m. #{seconds} s."
  end
