EDIT: Dead now, unless you live in San Diego.
As a kid, I used to love watching movies where office buildings or secret government bunkers had 10 clocks on the wall showing the time of cities around the globe. I used to wonder what people were doing in London or Tokyo or Nairobi at the same time I was brushing my teeth or sitting through math class. And while thismight not be as cool as having a clock for every time zone, it does the same job, which is all I care about.
