Again 2AM will be 3AM. All smartphones, tablets and other Spanish gadgets jump an hour at the time and suddenly, in Micheal J. Fox style, when the clocks are about to reach 2AM of Sunday 27th March they are turned forward 1 hour to Sunday 27th March, 3:00:00 local daylight time instead.
Watch out! Any device that is not “smart something ” will have to be adjusted manually.
This is not news but something still to be reminded.
Nevertheless, this fact arouses curiosity.
We call it Daylight Saving Time to advance and retard an hour on our clocks as we do every spring and autumn respectively. This is measure is held in about 70 countries worldwide. Even so, for example, if the day has 24 hours, Why are there up to 40 time zones? Why Japan is the only industrialized country that does not practice this change? And even more intriguing, what time is it in space?
It is paradoxical that the simplest answer has been to understand about the time off the planet Earth. Perhaps because of its scientific, empirical explanation with no political influence or economic interests (despite the redundancy).
In the case of the 40 time zones, this occurs because many countries are not limited to add one hour to Coordinated Universal Time ( UTC ) but add fractions as half an hour or 45 minutes. Such is the case of Nepal, for instance, which adds 5 hours and 45 minutes to universal time, only a quarter hour ahead its neighbors of India, totaling in 5:30 pm.
There is also the case of the State of Indiana (USA), where some students go through two changes of time on the bus ride to school and back home. Or Russia that only goes through only one Daylight Saving Time a year.
From an ordinance in 1886, which was issued in response to the confusion that arose after the adoption of means of transport, the Standard Time of Japan (STJ) was set to 9 hours ahead compared to Greenwich Mean Time (UTC was not established yet). It turns out, for example, that there are about 5 degrees difference in terms of length between Tokyo and Osaka, and because of this method of setting the time, a train out of Tokyo arrived at Osaka 20 minutes before the time in Tokyo.
Throughout history and around the world, there have been many reasons why a country or region have decided to apply specific adjustments to their watches. From the interests of farmers in the nineteenth century, through the oil crisis in 1973 up until today still open debate about saving energy or not by means of these time adjustments.
To finish and put it simple, it seems much less difficult to understand the special relativity of Newton than all these mismatches on terrestrial clocks.
Now the important and serious fact is that this past-midnight of Saturday 26 to Sunday 27, 2AM will become 3AM , Therefore, we are all sleeping one hour less in Spain.
