“What time is it? A seemingly easy question. But in any given
______
, the time will be different in different places in the world. While one person is
______
up to breakfast at 7AM, another will be
______
off to bed at 10PM. Local time all
______
on what time zone you’re in. A time zone is simply a region on
______
which is bound by longitudinal lines. These lines, sometimes called
______
, run vertically from the north to the south pole, each
______
degrees apart. Meridians break the world into
______
time zones. A time difference of one hour per
______
occurs with the rotation of the Earth. If it is, say 2PM at one meridian, 30
______
west will be two time zones, or two hours,
______
. So here, it would be high noon.
Between zones 0 and 24 lies the International Date Line where you
______
from one day to the next. But who decided what time it was, and where?
______
time it is now, it is the result of an historic event in 1884. At the International Meridian
______
, Canadian Sir Sandford Fleming proposed that time
______
at Greenwich, London, a major trade and
______
hub of the time. Using Greenwich as the
______
universal meridian, the 24 time zones were established. The system was known as Greenwich
______
Time. By 1929, most countries had
______
their clocks accordingly.
Because your body
______
is adapted to the time zone you live in, moving around the
______
into other time zones can affect you. If you travel from London to Los Angeles for example, you’ll be eight hours behind. This means you’ll be
______
when you should be sleeping and nodding off when it’s time to go out and
______
. The time on your
______
was set over a century ago but wherever you go, it will be constantly changing.”
