Binary clock with separate H:M:S.

Know a better way?

If you can do better, submit your command here.

What others think

Doesn't work on a Mac (10.6.1), which is saddening.

I installed watch and bc via fink and it worked fine. I imagine you could install those 2 packages by hand if you wanted.

A quick hack before going to work -- A readable binary clock

(clumsy, I know, but it works)

H=$(echo "obase=2; $(date +%H)" | bc); M=$(echo "obase=2; $(date +%M)" | bc); echo $H:$M

solaris version:

while :; do echo "obase=2;$(date +%I%M%S)"|bc; sleep 1; clear; done

Scroller* is an alternative to watch, that works fine on Mac OS X. :)

*= http://freshmeat.net/projects/scroller

curl -L -O http://downloads.sourceforge.net/project/scroller/scroller/1.0/scroller-1.0.tar.gz tar xvfz scroller-*tar.gz cd scroller* make sudo mv scroller /usr/local/bin/
