The Greenwich Meridian or the Prime Meridian is the imaginary line on maps from which all international times are calculated. Greenwich Mean Time (GMT). The time at every point on earth is calculated with respect to Greenwich Mean Time. This practice was originated for maritime navigation and meant that ships clocks needed to be extremely accurate and well maintained.
