Vista has a new feature that lets you have multiple clocks on your machine.It can save you considerable time and embarrassment in tracking times in other locations. Consider the problem of daylight saving time. Some areas of the world have this feature, others don’t. Even those areas that use daylight saving time don’t change time on precisely the same date. Consequently, tracking time in other areas of the world isn’t always a matter of adding or subtracting the required number of hours.
