Why do the Clocks Go Back? Understanding GMT

Every year, without much thought, we adjust our clocks twice: once in the spring to “spring forward” and again in the autumn to “fall back.” This seemingly simple act has a profound impact on our daily lives, from work schedules to social gatherings. But why do the clocks go back? And what is the significance of Greenwich Mean Time (GMT) in this process?

In this blog post, we will delve into the history and purpose of daylight saving time, explore the role of clocking-in machines in modern workplaces, and unravel the mysteries of GMT. By the end, you’ll have a deeper understanding of why our clocks keep changing and how this practice affects our lives.

The Origins of Daylight Saving Time

To effectively answer the question ‘Why do the clocks go back?’, we must first understand the fascinating history behind this collective ritual.

In the 18th century, while serving as the U.S. ambassador to France, Benjamin Franklin proposed a radical idea: shifting the clocks forward during the summer months to align with the longer daylight hours. His motivation was simple: to conserve candles, a precious and expensive commodity at the time. While Franklin’s proposal didn’t gain immediate traction, it laid the groundwork for the concept of daylight saving. It was a testament to his innovative thinking and his belief in the power of optimising our use of natural resources.

Fast forward to the early 20th century, and we find William Willett, a prominent businessman, amateur astronomer, and great-great-grandfather of Coldplay’s Chris Martin, in the UK, championing the cause of daylight saving.

Inspired by Franklin’s idea and his own observations of wasted daylight during summer evenings, Willett believed that shifting the clocks forward could lead to significant energy savings and promote outdoor activities. Namely, he was frustrated that his games of golf were being cut short by the setting sun, and sought to start them earlier to counteract this.

Willett’s persistence and advocacy would eventually pay off after his unfortunate passing in 1915, though not as a result of his love for golf. In the middle of the First World War (1916), the UK adopted British Summer Time (BST), aping the Germans who had already done so to conserve energy, marking a significant milestone in the history of daylight saving.

Simply put, the clocks go back at this time of year to align with the natural shortening of daylight hours. As we move closer to winter, the days become progressively shorter, and the sun sets earlier. By turning the clocks back, we ensure that our artificial collective timekeeping system better corresponds to the natural rhythms of the day.

This adjustment also has practical benefits. It allows us to wake up to natural daylight and enjoy longer evenings. It can also help reduce energy consumption, especially during the winter months when artificial lighting is used more frequently.

Understanding GMT

Greenwich Mean Time (GMT), often referred to as Universal Time Coordinated (UTC), is the primary reference point for timekeeping worldwide. Its significance lies in its role as the foundation upon which other time zones are established.

The Royal Observatory in Greenwich, London, is the birthplace of GMT. Situated on Prime Meridian, a longitudinal line that divides the Earth into eastern and western hemispheres, the observatory has played a crucial role in determining the exact time since the 17th century.

To accommodate the Earth’s spherical shape and the varying daylight hours across different longitudes, time zones were introduced. These are standardised regions that share the same official time. GMT serves as the reference point for these time zones, with countries adjusting their clocks to align with their geographic location relative to the Prime Meridian.

GMT’s significance extends beyond mere timekeeping. It is essential for coordinating global activities, such as international flights, satellite communications, and financial transactions. By providing a universal standard for time, GMT ensures that people and businesses around the world can operate on a synchronised schedule.

The Importance of Daylight Saving Time today

While the original motivation for daylight saving time (DST) was to conserve energy, its significance has evolved over time. Today, it serves a variety of purposes, including promoting outdoor activities, reducing the need for artificial lighting, and aligning with natural rhythms.

By shifting the clocks forward, DST extends daylight hours in the evenings, encouraging people to spend more time outdoors and engage in activities like exercise, gardening, and socialising. This can lead to improved physical and mental health. Additionally, with more daylight in the evenings, people can rely less on artificial lighting, potentially leading to energy savings and reduced carbon emissions.

However, DST is not without its critics. Some studies suggest that it can disrupt sleep patterns, leading to increased fatigue, irritability, and even health problems. Additionally, there are concerns about its potential impact on the environment and animal behaviour. Given the mixed benefits and drawbacks of DST, there is an ongoing debate about whether it should be discontinued. While some advocates argue for its continued use, others believe that it’s time to abandon this outdated practice. But for now, DST remains a part of our annual routine.

And now, when you’re asked by a friend or colleague ‘Why do the clocks go back?’, you’ll be able to provide them with an accurate and well-informed answer that doesn’t rely on the many cultural myths that have been perpetuated over the decades.

The Role of Clocking-In Machines

In today’s fast-paced business environment, accurate timekeeping is essential for efficient operations and compliance with labour regulations. This is where clocking-in machines play a vital role.

Clocking-in machines are electronic devices that record the precise time when employees arrive at work, leave for breaks, and depart at the end of their shifts. These machines provide a reliable and efficient way to track employee attendance and ensure that payroll calculations are accurate. For businesses with employees working shifts or adhering to strict timekeeping policies, accurate timekeeping is crucial. It helps to prevent overtime disputes, ensure compliance with labour regulations, and improve productivity.

By accurately recording employee hours, clocking-in machines can help prevent disputes over overtime pay and ensure that businesses are compliant with industry-specific regulations. Additionally, by tracking employee attendance and identifying patterns of absenteeism or lateness, businesses can take steps to address any underlying issues and improve overall productivity.

Important Note: Adjusting for GMT

With the upcoming transition to GMT, it’s essential for businesses to ensure that their clocking-in systems are correctly adjusted. Failure to do so can lead to inaccurate timekeeping and potential compliance issues.

Check your time and attendance systems settings to verify that they are configured to use GMT. This will ensure that your employee time records are accurate and aligned with the official time standard.
