Eventhough this can be implemented in several way's, I need the simpler one. Any idea would be much appreciated.

Thanks in advance,

08366 will be greater than 08100 which will be greater than 08001.

You can use a simple -gt construct.

Code:
if [[ $ldate -gt $rdate ]] ; then
  echo "$ldate is greater is than $rdate"
fi ;

       -s     Set the system time to the returned time.
