Angry at the waste of daylight during summer mornings, he self-published a pamphlet called "The Waste of Daylight". The UK did the same a few weeks later, along with many other nations involved in the First World War Within a few years of its introduction, many countries across the world adopted Daylight Saving Time. However, the benefits of it have been an ongoing debate since it was first introduced.
During the winter, clocks were kept one hour in advance of GMT to increase productivity. With the war over, Britain returned to British Summer Time except for an experiment between and when the clocks went forward but were not put back.
The experiment was discontinued as it was found impossible to assess the advantages and disadvantages of British Summer Time. Campaigners have sought a return to British Double Summer Time or a permanent British Summer Time to save energy and increase the time available in the evenings.
Opponents pointed out that in the north it would create social disadvantages: for instance, in the far north-west of Scotland sunrise would occur at about 10am in winter, and over much of the north children would have to travel to and from school in darkness. The British Summer Time Act was created in which started the tradition of changing the clocks in late March subject to the date of Easter and late October. Twenty years later, the changing of the clocks in Britain was aligned with other European countries and from onwards, the EU stipulated that all member states should adjust their clocks on the last Sunday in March and October.
Iceland is exempt from this directive, due to its northerly latitude and extreme variations in daylight and darkness throughout the year. However, in March the European Parliament backed a proposal to end the practice of changing the clocks in European Union states. Difference Between Similar Terms and Objects. MLA 8 M, Emelda.

Initially, the logic behind the clocks changing was to save energy and get people outside , based on the logic that it was pointless to waste electricity when there was perfectly good daylight to be used.
The campaign for British Summer Time came about at the beginning of the 20th century. Moving the clocks forward in the summer months would give us darker mornings but lighter, longer evenings. Since then, Britain toyed with moving the clocks a number of times, including bringing them forward two hours ahead of GMT during the Second World War. They were also brought forward for periods in the spring of , in line with fuel shortages. There was an experiment, between and , which kept clocks one hour ahead of GMT all year round.
Britain then reverted to our now familiar system of GMT in the winter and summer time in between March and October. Britain was a shipping leader in the 18 th century. During one naval expedition Britain lost men due to incorrect coordinate calculation. This led to people actively seeking the solution to the problem of longitudes.
At that time Royal Observatory at Greenwich was already established. It had a pendulum clock that showed the solar time at Greenwich. It was mostly used by star gazers. The problem of longitudes was solved when mariners found out that they could accurately calculate their coordinates at sea when they kept one chronometer set to the GMT.
This was possible because GMT showed the time at zero degree longitude i. Other countries followed suit and started recognizing GMT as the international standard time.
