We have all experienced the confusion of travelling to another country and finding we have to change time. Confusingly either moving time forward and losing precious moments or moving time back and repeating time we have already lived.
In order to measure time it was globally agreed to have a starting point. Noon was decided on, when the sun is highest in the sky. As this occurs at different times around the world, as the earth rotates, it was decided that a point of reference was required. This became known as Greenwich Mean Time (GMT).There are 24 time zones and each zone represents one hour.
The International Date Line (IDL) is an imaginary line on the opposite side of the world to Greenwich which is near London, England. If you cross the line heading west you add a day however if you are travelling east you go back a day and technically arrive before you left!
Modern day clocks and watch companies strive to improve technology in order to keep perfect time. From
Seiko Watches through to Dolce and Gabbana, manufacturers constantly try to perfect innovative ideas in order to create the most accurate timepiece.
