                   Significance of Greenwich mean time

• The ‘Greenwich Mean Time’ (GMT) is the time that can be measured by the help of “Earth’s zero degree” line of longitude, or meridian.

• This line called the Greenwich Meridian runs from the ‘North Pole’ to the ‘South Pole’ and passes through the ‘Old Royal Observatory’ in Greenwich, London.

• If a country lies west to the meridian, then the time will be behind and will lose from the GMT.
• If a country lies east to the meridian, then it will be ahead of GMT and will gain time.
