Tomorrow is the date at which the clocks go forwards by one hour, moving us instantly from Greenwich Mean Time (GMT) to British Summer Time (BST).
This has been happening every year since the Summer Time Act was passed by Parliament in 1916, whilst the Great War was raging in Europe. Placing the clocks an hour ahead gave workers an extra hour of daylight in the evening, enabling greater productivity for the war machine.
After World War One the annual changes to the clocks continued ping-ponging back and forth between BST and GMT.
World War Two started in September 1939, and by 1941 the UK was on Double Summertime (DST). This was achieved by putting the clocks forward in spring 1940 and not putting them back to GMT at the end of Autumn. In spring 1941, the clocks were advanced by an hour again – giving even more daylight to aid productivity.
This went on until autumn 1947, when the clocks went back completely to GMT.
Despite a parliamentary enquiry conducted in the late 1950s, involving 180 organisations, which concluded that there was a slight preference to remain on GMT +1 throughout the year, Britain stayed with the system
Why am I telling you all this?
Well, its because I’m in two minds about this.
Research conducted by the University of Colorado (Boulder) has shown conclusively that the fatal car accident rate spikes by 6% during the working week following the clocks being moved forward into Daylight Saving Time (DST). As the research only studied fatal accidents, it may be reasonably assumed that the underlying rate for all accidents will increase.
A further study published by Vanderbilt University’s Medical Unit shows that there is a negative impact upon health during the transition from statndard time to daylight saving time.
The cumulative effects of Daylight Saving Time can lead to increasing risks of heat attacks and ischaemic strokes
It appears that its not just the biannual one hour difference interfereing with our “body clock” or Circadian Rhythm – but the cumulative effects of this misalignment which takes up about eight months of the year.
It is the actual process of changing rather than which time reference is followed.
The European Union (EU) has voted to end Daylight Saving Time in autumn 2021. States within the EU have the choice of making their last change on the final sunday of March, or the final sunday of October, depending on whether they wish to have their standard time based on summertime or wintertime. This would naturally accommodate preferences according to geographic location.
So – moving the clocks back and forward is bad for health, and bad for accident rates.
On the other hand, there is a big argument for doing something more radical.
Lets stay on GMT+1 as our standard time.
Moving the clocks forward every spring, as we did in WW2, gives us effectively two hours more sunlight in the evening during summer, and one more hour of evening light in the winter.
Looking at this from an environmental perspective; extra light means less electrical demand for lighting in the summer, and during the winter months less demand for heat as well.
Research conducted by Cambridge University showed that an extra hour of sunlight every day during winter could save up to £485M ($604M US) annually.
A further benefit is a proportionate reduction in carbon emissions as well.
Now, lets think about trade. Disregarding Brexit, we still do a lot of trade with our neighbours in the EU. However, even the most western part of the continent is always an hour ahead of the UK, and eastern states such as Finland are two hours ahead.
This is an impediment to easy trade, so staying GMT+1 in winter, and GMT+2 in summer would keep us aligned with our european trading partners.
Tourism would also receive a big boost, with longer hours available when people are not working.
The Tourism Alliance estimated that an extra £3.5M ($435.9 US) of revenue would be generated in the UK as a result iof businesses staying open for longer. This would create an estimated 80,000 jobs.
Individuals would also gain about 235 hours of post-work daylight every year,
Now that’s got to be worth having!
What would people do with all of this extra daylight? Well., they would use the opportunity to play sports, visit parks and enjoy outdoor recreational activities.
This has a health benefit, as more people out exercising (Even if they are only walking or cycling to the pub!) means less people becoming unhealthy as a result of inactivity.
Human nature is such that we tend to stop outdoor activities when it gets dark. SImply readjusting our clocks so that “dark” coincides with “later” means we achieve more each day.
The extra hours of daylight could also reduce crime levels, as most criminals do like to do their “work” in the dark.
Well, I would like to use the old WW2 system of GMT+1/GMT+2. Ilike the idsea of an extra 235 useful hours every year. I like the idea of saving power and cutting emissions.
It does seem that on balance this could be the best option for business, the planet and us living on it.
