Question Report the current time in Binary format

Hey fellas,

I am trying to report the current time in a binary format which is overwriting every second. So far I wrote following script which I know looks stupid since I'm a newbie! Smilie

Code:
#!/bin/bash
while true;
do 
	clear; 
	date | 
	awk '{print $4}' | 
	awk -F ":" '{print substr($1,0,1) "\t" substr($1,2,1) "\n" substr($2,0,1) "\t" substr($2,2,1 )"\n" substr($3,0,1) "\t" substr($3,2,1) }' ; 
	sleep 1; 
done

As you see the output is a table like this:
1 3
4 9
0 8

I want to convert this to a binary format to have an output like this:
0001 0011
0100 1001
0000 1000


I know the following command turns a given digit into binary format:
Code:
echo 'obase=2;<digit>' | bc

But I don't know how to use this or any other ways of conversion in a while loop in my script.

Thanks in advance for your kind helps! Smilie
