This is a really good world clock application that one of my traders, Owen, told me about (there's also a 'pro' version available).
It basically puts 4 world time zones in small text boxes on your monitor, and you can locate them anywhere you want. Very well-done, and it has lots of positive reviews at download.com .. there's a free one to check out, plus a paid one that has FX data as well -- here's the link:

Thanks again to Owen for bringing it to my attention -- check it out!
