Greenwich Mean Time. Greenwich, just outside London, England sits on Longitude 0. All sea traffic took it's timing from Greenwich. Sir Sanford Fleming, a Canadian, proposed in 1878 that the world adopt a common system of time measurement focused on a central point. Consequently, there are 24 time zones around the world, 12 in advance and 12 after GMT. They were set as 1 hour intervals per 15 degrees of longitude. On large continents that rigidity is unfeasible, some states would be divided into 2 time zones. So for ease of management, congress sets the demarcation lines of the 5 US time zones. The 3 Australian time zones are similarly managed. Because the lines of longitude converge at the poles, the 24 time zones become as one. Therefore UTC (Coordinated Universal Time) is used there.
