700 Common Words Exercise No. 17
When some time ago we were giving a little thought to
the strange nature of Time, we let ourselves take some comfort from the
certainty that at least we knew that each day was made up of 24 hours. A day,
we lightly stated, had in it just 24 hours, never 23 and never 25. But were we
right in thinking that we knew this to be the case? Perhaps not, for when the
expert comes along he informs us that a day lasts 48 hours and at the same time
does not exist at all. We open our eyes a little wider with surprise and ask:
How can such things be? And we are given a quite simple reason. As we all
learned at school, our earth is always turning away from the west, and the
nearer a place is to the east the earlier is the hour of day-break at that
place. If, for example, we were living in a country at a point on the earth
where the distance round the world is as great as it can be, and we were to
leave that country and go to another country which is, let us say, a little
over one thousand miles more distant round the world) we would find that day
break was an hour earlier in our new home than it had been in our old home. If
we moved only five hundred miles towards the east we would find the difference
to be only half an hour, and if we moved only 50 miles we would find the
difference to be as little as three minutes. If we look at a table of lighting
up times we note that these times differ widely for different parts of the same
country. But long, long ago, before the present age with its planes and TV, men
found that any form of exchange between nations was made very difficult when
there was no order in the method of stating the time in different parts of the
world. So, to make it possible for anyone in any part of the world to know just
what time it was in any other part of the world, the following course was
agreed upon. Man had already cut up the day into 24 hours, and he now agreed to
cut up the earth into 24 division each division, of course, measuring about one
thousand miles at its widest point. The time over the whole of each division
was to be the same, the time in each division differing by just one hour from
the time in the next division. We, therefore, have a system whereby the minutes
and the seconds are the same all over the world, but the hour is one hour
earlier for each division as we move towards the east. Now we will say that in
the “first” of these divisions New Year’s Day begins. Hour by hour New Year’s
Day reaches and passes through one of the 24 divisions until at the end of 24
hours it is in the last division. By that time the day is coming to an end in
the first division, and the second of January is beginning. But the last
division, too, must have its full day and 24 hours must pass before New Year’s
Day really comes to an end and dies in the last of the 24 divisions. The first
of January lives for 48 hours. But while the first of January has been
continuing its life in this way the second of January has been moving round the
world. The first hour of the second of January reaches the last division just
as the 24th hour of the first of January dies, and at the same moment the third
of January begins in the first division. And so we are faced with the strange
truth that while a day lasts 48 hours there is between the first and 3rd of
January no break at all. People in one country can hear “Five Hours Back”
coming to them over the air, hearing in another country. And the people of that
country can have the equally remarkable experience of hearing “Five Hours
Forward.” They can hear the people of another country “seeing the New Year in
“while it is for them the early evening of the last day of old year. And if we
are covering a long distance by ship we have the experience of finding that a
certain day can last only 23 hours or for as long as 25 hours!.
