On December 12th, 2012, at exactly 12:12:12, I captured a fleeting moment that will never come again. Thanks to Aaron and his atomic clock, we could mark this exact time with a photograph taken atop a parking garage in Baltimore, Maryland. The building in the shot acted as a sundial, casting shadows that aligned perfectly with the symbolic moment. This snapshot is a follow-up to last year’s similar capture at 11-11-11 11:11:11. It’s a simple but meaningful way to remember these special times when numbers and time are aligned.
