If you need to quickly check the time in another country or city then InstantTimeZone could be your saviour. Simply by rolling your mouse over an icon on your System Tray, the full time (with minutes) is diplayed, along withthe date.

You can run many instances of InstantTimeZone at the same time, displayed in different colors, to show the times in multiple time zones. Plus, there are several other options available, including the ability to add years and dates for countries with different calendars and dates, such as China or Thailand.
