These two solutions would help pave the way for GMT to become the worldwide time standard a little more than a century later. This meant they could calculate their longitude from the Greenwich meridian (also referred to as the вЂњPrime meridian,вЂќ or longitude 0В°).

In 1767, the fifth Astronomer Royal, Nevil Maskelyne brought Greenwich Mean Time to a wider audience by introducing the Nautical Almanac as part of the great 18th-century quest to determine longitude.Д«ritish mariners started keeping at least one chronometer set to GMT. Soon after, John Flamsteed was appointed as the first Astronomer Royal and moved into the new Royal Observatory. Highly acclaimed British architect, Christopher Wren was commissioned to design the domed building. In 1675, King Charles II offered the land to The Royal Society for BritainвЂ™s first national observatory. Greenwich was a royal park and palace on a hill to the south of the River Thames east of London, England. It wasnвЂ™t until the invention of the pendulum clock in the 1650s that it was possible to work out the relationship between mean (clock) time and solar time.Д«ritish astronomer, John Flamsteed came up with the formula for converting solar time to mean time, and published a set of conversion tables in the early 1670s. GMT was originally set up to aid naval navigation when travel around the globe started to open up with the exploration of the вЂњNew WorldвЂќ (America) during the 16th century. ItвЂ™s a way to standardize time so we can all know exactly what time it is for any location.

If you own a sundial for instance, youвЂ™re aware that вЂњnoonвЂќ based on the position of the Sun can differ by as much as plus or minus 15 minutes from what a clock may read.Д«ut each day measured by a clock has the same length, equal to the average (mean) length of a solar day. It differs from solar or astronomical time clock time because solar time varies throughout the year. In essence, вЂњmean timeвЂќ is what you would read off of a clock.

YouвЂ™ve heard of Daylight Saving Time, Standard Time, Eastern, Central, Mountain, and Pacific Time, but have you heard of the term Greenwich Mean Time, sometimes referred to simply as GMT, or Coordinated Universal Time (UTC), and wondered what the heck it is?
