have a complete set of clocks one for each time zone which allowed me to add unlimited names to each clock with the country of each individual for use with social networking.

Either as a page full or a vertical or horizontal string, each time zone would be represented by a clock and all clocks could be seen at the same time. Each clock would have a form attached to it which the user could fill in with the name and country of any number of individuals. When using social networks or doing business worldwide the user could check the time in the country of any contact (including by using a search engine included on the page or string.) or just hovering over the clock faces to see the lists of people whose details have been added. As an added nicety you could make it so that the clock faces indicated at a glance whether it was day or night in each zone...
