It's About Time |
Designed by Sir Christopher Wren and built 330 years ago, The Royal Observatory, home of Greenwich Mean Time and the Prime Meridian lines is one of the most important historic scientific sites in the world.
The Meridian is an imaginary line which runs from the North Pole to the South Pole. It runs through the main telescope at the Royal Observatory in Greenwich, south-east London.
The point is known as Zero Longitude and it is the line from which all other lines of longitude are measured. 00° 00' 00""
On Crystal Serenity's World Cruise in 2011, we crossed the international dateline, or IDL.
The International Date Line (IDL) is an imaginary line on Earth's surface defining the boundary between one day and the next.
The International Date Line is located halfway around the world from the prime meridian (0° longitude) or about 180° east (or west) of Greenwich, London, UK, the reference point of time zones.
The cognitive dissonance is sorted.
