states adopted the Pacific, Mountain, Central, and Eastern time zones by 1895, Congress did not mandate their use until the Standard Time Act of 1918. The conference designated Greenwich, England’s longitude as zero degrees and established 24 time zones based on the prime meridian.ĭespite the fact that the time zones had been established, not all countries promptly switched. In 1884, a conference was convened in Washington, D.C., to standardize time and choose the prime meridian. On November 18, 1883, railroad companies in the United States began using Fleming’s standard time zones. Sir Fleming’s time zones were hailed as a brilliant universal solution to a chaotic problem. Since the earth rotates once every 24 hours and there are 360 degrees of longitude, the earth rotates 15 degrees of longitude each hour. He suggested that the globe be divided into 24 time zones, each separated by 15 degrees of longitude. In 1878, Canadian Sir Sandford Fleming proposed the current system of global time zones. History of The Standardization of Time Zones Typically, your country’s government or an astronomical institute defines time zones, which are represented by three or four letters. In addition, we have Daylight Savings Time, which is also a Time Zone variation, in order to save energy. Occasionally, individuals in not-so-distant locations require the same time as those in not-so-distant locations, so the division is now much more political than geographic. The Time Zone is a geographical world globe division of 15o each, beginning at Greenwich, England, designed to assist people in determining what time it is in another part of the world. The General Time Zone converts between all time zones that enable the Chicago time zone. It converts Chicago time to the local time in other time zones. In Connecticut, timepieces are typically adjusted annually (once forward and once backward each year). It is either one or the other, depending on the season. This time zone is divided into two “sub” time zones, CST and CDT. Within this time zone are numerous cities and states.
