Pop Quiz - The Reveal

I posted a Pop Quiz about 3:00 pm today. Now, as promised, I bring you The Reveal (the answer).

First, I must tell you this is a binary clock, so it works on powers of two. And I know of several different versions of binary clocks, but I can only speak for my own, so here we go ...

The clock:



This clock is divided into three sections, each with two rows of lights. Left to right, the left-most two rows represent the hour, the middle rows represent the minutes, and the right-most two rows represent the seconds.

On my binary clock, reading from bottom up, the lights represent 1 (2 to the zero power), 2 (2 to the 1st power), 4 (2 to the 2nd power), and 8 (2 to the 3rd power). So we have 1,2,4 and 8 to work with (with which to work).

The hours columns of lights have the 2 and the 1 lit up, which equals 03.

The minutes columns have no lights on, so it's :00. So far we have 03:00.

The seconds columns have 2 & 1 on the left, and 2 on the right, which represents :32, giving us 03:00:32.

So Anonymous & Lisa - Papergrace were indeed correct with their guesses! Congratulations!
Unfortunately, you win nothing but the knowledge that you are very, very, smart. :-)

Thanks for playing, everyone!

I thought I commented...did it get lost? Hmmm...

Anyway, I've seen these clocks in magazines that I receive, but just couldn't remember EXACTLY how they worked so I looked it up. I'm not so smart after all. Sorry. :( Hope you're not disappointed in me.
