Microsoft Time Zone installs as a small tray icon that allows you to specify as many as five cities to watch the time on while you are working on your computer. In order to schedule meetings and trip the Microsoft Time Zone application also lets you compare times at different places in the world without changing your system time.
Requires .NET Framework 1.1 and Windows XP. This tool is wonderful as now I can fix times for chat and work with friends around the world with ease.
