>> Hi:
>>
>> http://www.standard-time.com/index2_en.php
>> 4 x 12 meter 7-segment display where the segments are boards held in
>> place by C-clamps.  One man can change one segment, but it takes 11 men
>> and a couple of ladders to change two digits.  If fewer (wo)men were
>> used the time to make a change would be longer than 1 minute and the
>> clock not be good to a minute.  It looks like they started out using 4
>> bolts at each joint with power tools and later changed to multiple
>> C-clamps.  You can buy a DVD movie  that can be played on a PC where the
>> video is synchronized to the PC time.  For more interesting On Line &
>> Hardware Clocks see:
