joeyg's answer is MUCH easier than coding this:
Code:
#!/bin/ksh

# two parms
# $1 = number of hours
# $2 = date in YYYY mm dd hh mi ss format
# prints  1 if date is older than  now minus <number of hours>
# prints 0 when not older
isolder()
{
	ago="$1"
	echo "$2" | sed 's/\./ /g' | sed 's/-/ /g' | read dt
	perl -e  ' 
	        use Time::Local;
	        $then = time - ( $ARGV[0] * 3600);
	        $testtime =
	           timelocal( $ARGV[6], $ARGV[5], $ARGV[4],
	                      $ARGV[3], $ARGV[2]-1, $ARGV[1]-1900);
	        $result = 0;
	        if ( $testtime < $then )
	        {
	            $result = 1;
	        }
            print "$result\n";
	        '  $ago  $dt
}

dt="2008-10-21 10.54.37"
# sample usage:
result=$(isolder 48 "$dt" )
if [[ $result -eq 1 ]] ; then
  echo "$dt is older than 48 hours"
else
  echo "$dt is not older than 48 hours"  
fi  
dt="2008-10-19 10.54.37"
result=$(isolder 48 "$dt" )
if [[ $result -eq 1 ]] ; then
  echo "$dt is older than 48 hours"
else
  echo "$dt is not older than 48 hours"  
fi
