A site I refer to pretty frequently is The World Clock. It's not the sexiest site out there, but it is reliable, useful, and timely (that's a pun. c'mon, grin a little). I especially admire the meeting planner component, for yes, planning meetings. The site is appealing for increasingly globalized interactions in real-time, and it pulls information from databases in a way that seems to scream logic and dorkiness, part of what I sincerely love about itp.

To follow the the dorkiness mention above, I also wanted to include Dorkmag.com. I'm a fan of this one for several reasons: 1- I like the guys who started it and their personal, low key approach to the project, 2- The construction is simple and designed w a subtle taste 3- the content is easily digested and spills into a nice mix of topics.
