the first clock
B.C. 742
First authentic recorded mention of the sun dial. There is, however, evidence of use of the sun dial as early as 2,000 B.C. the sun dial produces a shadow on the dial to tell the time of day \http://www.howardmilleronline.com/clocks/historyofclocks/
almost all other info came from a specific website on each event and that was from 40 different sites so i only put afew down through out the timeline -
