THE SUBJECT OF THIS CARD IS:
TIME ZONES WERE STANDARDIZED AND GMT ADOPTED IN 1884
The expansion of transport and communication during the 19th century created a need for a unified
time-keeping system, and time zones were introduced.
Britain  helped gather international consensus for global time zones in 1884.
Various meridians were used for longitudinal references among different countries before the late 1800s,
and the Greenwich Meridian was the most popular of these.  The International Meridian Conference in
Washington DC, USA, adopted a proposal in October 1884.The proposal stated that the prime
meridian for longitude and timekeeping should be one that passes through the center of the transit
instrument at the Greenwich Observatory in the United Kingdom (UK). The conference established the
Greenwich Meridian as the prime meridian and Greenwich Mean Time(GMT) as the worlds time
standard. The international 24-hour time-zone system grew from this, in which all zones referred back to
GMT on the prime meridian.
