Multi Zone Clock is a simple and highly configurable multi time zone clock and calendar plus highly configurable advance alarm clock. This Program creates any number of clocks with deferent time zones and many more . Give it a try and enjoy :P
A nice little program. It loads in the system area of the task bar, and when you click the icon, a rectangle appears, displaying the date and time for the time zone that's configured for that icon. You click the icon again to make the rectangle disappear. Not very well integrated with the task bar though. It needs the taskbar to be at the bottom of the screen to work properly, and its system area icons go into the "normally hidden" section. (I'm running Win7-64.) Also, there's no installer. But it's a nice-looking and useful utility.
Simple and good....
