Active World Clock allows you to display local time in multiple locations - branch offices or major client sites. The web part supports multiple look and feel options and clock templates, including analog clocks and digit clocks. The time calculation mechanism also accounts for the latest rules of daylight savings time and display the adjusted time automatically. In addition to supporting multiple presentation interfaces and look and feel options, the World Clock Web Part allows you to specify the size of each clock, direction (vertical or horizontal), and whether to display seconds for each clock. You can also re-order the clocks to match your requirements.
