Cleveland Abbe
In order to compile his information, Abbe required a time-keeping system that was consistent among the stations. To accomplish this he divided the United States into four standard time zones. He published, in 1879, a paper titled "Report on Standard Time". In 1883, he convinced North American railroad companies to adopt his time-zone system. In 1884, Britain, which had already adopted its own standard time system for England, Scotland, and Wales, helped gather international consent for global time. In time, the American government, influenced in part by his 1879 paper, adopted the time-zone system.
Time in Chile
"Summer time in Chile", also known as "daylight saving time (DST) in Chile" was used in Chile from 1968 to 2014 & 2016-present. The time zone "Chile Summer Time (CLST)" was used on the mainland with the offset and "Easter Island Summer Time (EASST)" was used on Easter Island with the offset . In mainland Chile, time was changed at on a Saturday, i.e. at 0:00 on the following Sunday. In Easter Island, time was changed at 20:00 on a Saturday. In 2015, the time offset used in this time zone eventually became the only time zone in Chile.
