British clocks gradually standardised to GMT from the 1830s because of the needs of the railways, but it was Victorian politicians’ concerns about licensing hours that led to legislation. An international conference in 1884 proposed Greenwich as the world’s prime meridian. The fallout was immense. For decades, the definition of time in France was ”Paris Mean Time retarded by nine minutes and 21 seconds’’ – Greenwich Mean Time by another name, and a splendid piece of diplomatic footwork. Arguments still rage over time zones.
Time is scientific concept and objective and somehow feels should be not decided by people’s opinions and politics, yet it has been debated for over 100 years.
