In our online Forex trading community we have had traders from the U.S., Canada, Mexico, Jamaica, Costa Rica, Virgin Islands, England, France, Switzerland, Sweden, Denmark, Croatia, India, Israel, Singapore, Hong Kong, Australia, New Zealand, etc all joining together for live trading sessions. Sometimes it is mentioned that the traders in one part of the world are going to bed while in other parts of the world traders may be starting their days. I like to have a world clock on my computer that shows the current time in various cities around the world in order to know what time it is when I may be contacting traders in other countries.
The Zonetick world clock is the one I like the best. http://zonetick.com/ This clock can be in the tray on the bottom of your computer where your regular computer clock is. Or you can have the clocks stacked up on your desktop as I do here:

The clocks have several nice skins and you can have each one light up during business hours or trading hours in that city. There is a nice list of features and the zonetick clock is much nicer than the other that I have tried which is Qlock. The Qlock world clock for the desktop is clunky and ugly compared with the cool and nifty Zonetick clock. And that is why I highly recommend it.
