Countdown timer with seconds

I would like this to work with seconds as well.

Code:

#!/bin/bash
# 
 
if [ "$#" -lt "2" ] ; then 
    echo "Incorrect usage ! Example:" 
    echo './CountDown.sh -d  "Jun 10 2011 16:06"' 
    echo 'or' 
    echo './CountDown.sh -m  90' 
    exit 1 
fi 
 
now=`date +%s` 
 
if [ "$1" = "-d" ] ; then 
    until=`date -d "$2" +%s` 
    sec_rem=`expr $until - $now` 
    echo "-d" 
    if [ $sec_rem -lt 1 ]; then 
        echo "$2 is already history !" 
    fi 
fi 
 
if [ "$1" = "-m" ] ; then 
    until=`expr 60 \* $2` 
    until=`expr $until + $now` 
    sec_rem=`expr $until - $now` 
    echo "-m" 
    if [ $sec_rem -lt 1 ]; then 
        echo "$2 is already history !" 
    fi 
fi 
 
_R=0
_C=7
tmp=0
percent=0
total_time=0
col=`tput cols`
col=$[ $col -5 ]

while [ $sec_rem -gt 0 ]; do 
    clear 
    date 
    let sec_rem=$sec_rem-1 
    interval=$sec_rem 
    seconds=`expr $interval % 60` 
    interval=`expr $interval - $seconds` 
    minutes=`expr $interval % 3600 / 60` 
    interval=`expr $interval - $minutes` 
    hours=`expr $interval % 86400 / 3600` 
    interval=`expr $interval - $hours` 
    days=`expr $interval % 604800 / 86400` 
    interval=`expr $interval - $hours` 
    weeks=`expr $interval / 604800` 
    echo "----------------------------" 
    echo "Seconds: " $seconds 
    echo "Minutes: " $minutes 
    echo "Hours:   " $hours 
    echo "Days:    " $days 
    echo "Weeks:   " $weeks 

    echo -n "["

    progress=$[$progress + 1]
    if [ $total_time -lt 1 ] ; then
        total_time=$[$hours * 3600 + $minutes * 60 + $seconds]
    fi
    
    printf -v f "%$(echo $_R)s>" ; printf "%s\n" "${f// /=}"
    _C=7
    tput cup 7 $col

    tmp=$percent
    percent=$[$progress * 100 / $total_time]
    printf "]%d%%" $percent
    change=$[$percent - $tmp]

    _R=$[ $col * $percent / 100 ]

    sleep 1
done
printf "\n"

   Friends
       std::ostream & operator<< (std::ostream &s, relative_time t)

Detailed Description
       Time interval.

Constructor &; Destructor Documentation
   shevek::relative_time::relative_time (timetypeseconds, unsignednanoseconds)
       Fast constructor. This directly fills the members and is therefore slightly faster than the other constructors. However, the others aren't
       really slow either.

Member Function Documentation
   bool shevek::relative_time::operator!= (relative_timethat) const Compare two intervals. Note that this is rarely a useful operation, because
       minor errors may be introduced by computations.
   bool shevek::relative_time::operator== (relative_timethat) const Compare two intervals. Note that this is rarely a useful operation, because
       minor errors may be introduced by computations.
