Windows Vista has few redeeming qualities, in my humble opinion. Some users, however, may have the need to track multiple time zones for work or personal use. I use this tip to track the time in Arizona where my brother lives. Because they don't follow daylight savings time, I am forever confused about what time it is for him when I call.
Watch the short video below to learn how to quickly track up to three time zones if you are a Windows Vista user.
UPDATE: I just stumbled on this free utility from Microsoft [1] that gives Windows XP users the same ability described in my tip above that Vista users have...tracking multiple time zones. Yet ONE more reason NOT to upgrade to Vista.
