This is old post ovbioius -- but, for those who might are looking for the actual time elapsed but in military format (00:05:15:22 - instead of 0:5:15:22 )

!#/bin/bash
    num=$1
    min=0
    hour=0
    day=0
    if((num>59));then
        ((sec=num%60))
        ((num=num/60))
            if((num>59));then
            ((min=num%60))
            ((num=num/60))
                if((num>23));then
                    ((hour=num%24))
                    ((day=num/24))
                else
                    ((hour=num))
                fi
            else
                ((min=num))
            fi
        else
        ((sec=num))
    fi
    day=`seq -w 00 $day | tail -n 1`
    hour=`seq -w 00 $hour | tail -n 1`
    min=`seq -w 00 $min | tail -n 1`
    sec=`seq -w 00 $sec | tail -n 1`
    printf "$day:$hour:$min:$sec"
 exit 0
