Time is not the same

The time is not the same in the whole world, an we all know it. It is a different time in Washington and in London, or Ulan-Bator, and most of the time we don't need to realize that, but sometimes we do. Let's say that a friend of yours went abroad, or in to the other end of the country, or your boss sent you to the far away kingdom, or your brother is on holidays in Ethiopia, and you started to talk with some of them on a instant messaging program, or voice call program, and he tells you "Good morning!" at five o'clock in the afternoon. Then you start to ask yourself what time is it there (especially when it is your boss and you don't want to ask his time, you should add/subtract hours), but your head don't respond to your question. When you have a problem you solve it, you could create a table with your and theirs hours (me : 7 - boss : 11, bro' : 3 ...), or make your application, use something that exists already. I am lousy and I choose the las one. I found a MS TimeZone application that is very useful.

It looks like that when it is installed and runs in your system tray. And to perform this first step (the installation step), go here. The second step is to set your locations in options (right click on the tray icon) and your locations could be like this: To create your custom named locations just go in the Option dialog box to the add button under the Available locations list.

More informations about this application you can find here.
Or maybe you want a screen saver with time zones: here's a screen saver.
You could choose a less user friendly interface but mybe with some more power (i dont't realy know about it) by using this app.
One more thing: all these applications here are free, an work for windows.
