The Great Scot who devised international time zones and Universal Standard Time


Sir Sandford Fleming (January 7, 1827 – July 22, 1915) was an engineer and inventor. Born and raised in Scotland, he emigrated to colonial Canada at the age of 18.
After missing a train in 1876 in Ireland because its printed schedule listed p.m. instead of a.m., he proposed a single 24-hour clock for the entire world, located at the centre of the Earth, not linked to any surface meridian. At a meeting of the Royal Canadian Institute, on February 8, 1879, he linked it to the anti-meridian of Greenwich (now 180°). He suggested that standard time zones could be used locally, but they were subordinate to his single world time, which he called Cosmic Time. He continued to promote his system at major international conferences including the International Meridian Conference of 1884. That conference accepted a different version of Universal Time but refused to accept his zones, stating that they were a local issue outside its purview. Nevertheless, by 1929, all major countries in the world had accepted time zones.
In addition to proposing worldwide standard time zones, Fleming designed Canada’s first postage stamp, left a huge body of surveying and map making, engineered much of the Intercolonial Railway and the Canadian Pacific Railway, and was a founding member of the Royal Society of Canada and founder of the Royal Canadian Institute, a science organization in Toronto.
