Sanford Fleming: Inventor of Time Zones

Sanford Fleming played a key role in the development of a satisfactory worldwide system of keeping time. The railway had made obsolete the old system where every major centre set its clocks according to local astronomical conditions. Fleming advocated the adoption of a standard or mean time and hourly variations from that according to established time zones. He was instrumental in convening an International Prime Meridian Conference in Washington in 1884 at which the system of international standard time – still in use today – was adopted.
