Hi Juanito
You also have to change this:
	# For 24 hour format, comment the 12 hour line and uncomment the 24 hour line.
#	echo -ne `/bin/date +'%T'` > $TTY # Display the time (24 hour format)
	echo -ne `/bin/date +'%I:%M:%S%p'` > $TTY # Display the time (12 hour format)
	sleep 1
done
to this:
	# For 24 hour format, comment the 12 hour line and uncomment the 24 hour line.
	echo -ne `/bin/date +'%T'` > $TTY # Display the time (24 hour format)
#	echo -ne `/bin/date +'%I:%M:%S%p'` > $TTY # Display the time (12 hour format)
	sleep 1
done
