As British Summer Time winds down and we regain one hour, some may wonder what is behind this change? What is driving it forward?
Before the introduction of railways, most areas used local mean time; but following 1847’s Railway Clearing House’s introduction of standard time as Railway Time (RT), most areas switched over.
The Shepherd Master Clock
The Shepherd Master Clock was an impressive piece of technology that played an essential role in establishing Greenwich Mean Time. One of the earliest electric public clocks, it was installed here in 1852 as one of Charles Shepherd’s groundbreaking electric clock systems patented by George Airy for railway trains to use as references. Each town originally kept time by watching the sun or using sundials; but when Airy needed synchronized clocks that served as reference points he turned to Charles Shepherd and his groundbreaking system of clocks for reference purposes synchronization required him turning to Charles Shepherd with his pioneering electric clock system which Charles Shepherd had invented and installed here in 1852 as one of earliest electrically driven public clock systems ever installed anywhere worldwide!
Shepherd first invented and patented his system for controlling an intricate network of clocks using electricity (then known as galvanism) in 1849. By August 1852, it had been fully installed at the Great Exhibition and established as timekeepers within its observatory.
At the core of it all was the Shepherd master clock, which transmitted pulses every second to various clocks throughout the building – including Chronometer Room and Flamsteed House clocks – including those connected with London Bridge station via telegraph wires – providing time services to London and other cities around Britain – an early step toward national time signals that aligned with Greenwich Mean Time (GMT).
By the late 19th century, time signals from the Shepherd master clock had begun being transmitted via cable to various other locations across England – giving rise to Greenwich Mean Solar Time or GMT.
Notably, the Shepherd master clock still displays GMT today. While its minute and second hands still rotate the conventional way – once per hour and once every minute respectively – it now displays Greenwich Mean Time instead of civil time (which would create Daylight Saving Time or DST). Furthermore, its 920mm dial now divides 24 hours rather than 12 as was customary at that time.
Charles Shepherd must have felt anxious after returning from India and must have sought new opportunities afresh in London rather than Sydney Street or Chadwell Street. It appears he may have given himself up to new challenges; perhaps looking forward to new petty disputes between himself and his rivals was appealing to him. Based on the address listed for London rather than Sydney Street or Chadwell Street it seems likely he was looking for opportunities outside his previous locales.
Greenwich Mean Time
Greenwich Mean Time, more commonly referred to by its acronym GMT, is the standard time zone of the United Kingdom and five hours ahead of Coordinated Universal Time (UTC). Greenwich Mean Time does not change for Daylight Saving Time adjustments. Within the US it is commonly known as Eastern Standard Time.
Before the railways came to Britain, most areas kept to a local mean time which was determined by the sun’s rising and setting positions. As it took more time for it to reach Bristol than London, daybreak may occur later there as it hadn’t yet reached its highest point – making timekeeping harder as an effect of this phenomenon could vary considerably from location to location.
At first, clocks were used solely as timekeeping devices in the 17th century; it wasn’t until 18th century when standardised time was introduced due to navigation needs at sea. Charles II established the Royal Observatory at Greenwich Park near London to improve naval navigation; John Flamsteed became first Astronomer Royal. John Flamsteed created a method for calculating solar time as clock time.
By the 1850s, many railway stations had adopted Greenwich Time; however, this change was met with little enthusiasm by travellers and rail companies alike. Travellers complained of missed train connections while railway companies were accused of “railway time aggression.” To combat these complaints and accusations of railway time aggression, in 1855 the Railway Clearing House recommended all public clocks display Greenwich Time; eventually in 1880 this change became legal across Great Britain with Statutes (Definition of Time) Act legalising Greenwich Time as legal basis throughout Great Britain by 1880 statute.
Greenwich Mean Time (GMT) remains widely utilized across parts of Africa and Western Europe; however, the term is frequently confused with Coordinated Universal Time (UTC), the current international standard time zone. UTC represents time standardisation whereas GMT represents localized timekeeping.
Greenwich is home to the Prime Meridian, the zero degree longitude line in the world, making it home of the International Date Line as well as military and air force personnel who employ a more precise version known as Zulu Time.
Daylight Saving Time
Daylight Saving Time in the UK involves setting clocks forward an hour during spring and back one again during autumn to make better use of daylight and reduce energy use, but has generated much controversy; many oppose its implementation due to arguments such as disrupted sleep cycles, reduced productivity, confusion and accidents as a result of it.
William Willett (great-great grandfather of Chris Martin from Coldplay), was the first serious advocate of Daylight Saving Time when it was proposed in 1907. He published a pamphlet entitled The Waste of Daylight and spent much of his fortune campaigning ardently for its adoption during World War I as a way to conserve coal reserves. It was finally implemented during that conflict as an effective way of conserving energy supplies.
Although Daylight Saving Time certainly helps energy conservation, its effectiveness has not been widely acknowledged. Some studies have concluded that it has no measurable effect and even suggested potential health problems due to starting the day earlier than normal; such as reduced morning sunlight exposure that helps regulate our circadian rhythms and sleep; disruption of daily routines leading to stress and anxiety being just two possible consequences of switching times zones.
People are also concerned about how clock changes will impact animals and plants. Many fear that altering their circadian rhythms or disrupting natural sleeping patterns could result in diseases or even death; others speculate there could even be an association between clock changes and dementia.
Even with its controversial underpinnings, most of us have become used to the tradition of changing clocks twice every year. It has become part of our culture and there have been memes created about the issue. While some struggle with the transition, others welcome an extra hour of sunshine!
British Summer Time
British Summer Time, also known as Daylight Saving Time, occurs when clocks are advanced by one hour during summer to make more efficient use of daylight. It is currently observed throughout Europe and North America with most countries switching on or around the last Sunday in March until returning back on the last Sunday in October.
Daylight Savings was first proposed by builder William Willett during the 19th Century as he wanted longer evenings to play golf and equestrian activities. He claimed in his self-published pamphlet that Daylight Savings would reduce energy consumption, decrease railway accidents and boost productivity – yet his idea died with him when he passed away before becoming reality; but eventually it was adopted under the Summer Time Act 1916.
During World War II, Britain temporarily adopted British Double Summer Time two hours ahead of GMT; this practice was never reinstated postwar. Harold Wilson experimented with year round British Standard Time from 1968-1971 before backtracking after receiving feedback through free vote in Parliament.
Today, the Royal Society for the Prevention of Accidents advocates for year-round BST as they believe it can save lives by reducing road accidents at nighttime and expanding leisure time activities like playing sports or other leisure pursuits. They claim it could even reduce energy usage by 10% while decreasing air pollution levels.
BST remains an extremely controversial issue and likely to remain so for many years to come. Critics contend that Daylight Saving Time creates darkness in northern England and Scotland in the mornings, is difficult on farmers, causes health issues due to reduced sleep hours, and could increase risks such as heart attacks or strokes due to lost rest. On the other hand, supporters emphasize increased lighting for outdoor activities as well as reduced crime due to decreased criminal activity during darker hours. Whatever their decision, this fascinating piece of UK history remains an enjoyable topic of debate today.
