For us lazy people: ready-made script available at https://github.com/k0smik0/FaCRI/blob/master/fbcmd/bin/displaytime :

#!/bin/bash

function displaytime {
  local T=$1
  local D=$((T/60/60/24))
  local H=$((T/60/60%24))
  local M=$((T/60%60))
  local S=$((T%60))
  [[ $D > 0 ]] && printf '%d days ' $D
  [[ $H > 0 ]] && printf '%d hours ' $H
  [[ $M > 0 ]] && printf '%d minutes ' $M
  [[ $D > 0 || $H > 0 || $M > 0 ]] && printf 'and '
  printf '%d seconds\n' $S
}

displaytime $1

Basically just another spin on the other solutions, but has the added bonus of suppressing empty time units (f.e. 10 seconds instead of 0 hours 0 minutes 10 seconds). Couldn't quite track down the original source of the function, occurs in multiple git repos..
