Britain, which already adopted its own standard time system for England, Scotland, and Wales, helped gather international consensus for global time zones in 1884. Every city in the United States used a different time standard, so there were more than 300 local sun-times to choose from. Coordinated Universal Time (UTC) is the basis for civil time today. Believe it or not, until about the 19th century there were no central time standards. Time calculation became a serious problem for people traveling by train (sometimes hundreds of miles in a day), according to the Library of Congress. Even after the chronometer many towns and cities set clocks based on sunsets and sunrises. Hover your mouse over the map to highlight time zones.

There is an imaginary line running through the UK called the Prime Meridian. © Time and Date AS 1995–2021. Railroad managers tried to address the problem by establishing 100 railroad time zones, but this was only a partial solution to the problem. Time zones were, therefore, a compromise, relaxing the complex geographic dependence while still allowing local time to be approximate with mean solar time. Britain and France had each adopted national time standards decades earlier, but as they were smaller countries, there was no need for more than one-time zone. The International Date Line (IDL) on the map. Due to the size of some countries and the spread of other places belonging under their jurisdiction, one country can be divided into a number of time zones.

To maintain a fairly accurate railroad schedule, a time standard was absolutely necessary. The Full Moon in March is the Worm Moon.

Interestingly, many French maps showed zero degrees in Paris for many years despite the International Meridian Conference’s outcomes in 1884. The time convention begins with Universal Coordinated Time (UTC) which is also commonly referred to as Greenwich Mean Time (GMT) being located at the Greenwich meridian. Many nations today use standard time zones, but some places use 30 or 45 minute deviations from standard time. The successful adoption of standard time in the United States in 1883 set an example of how time zones could spread across the globe.

Britain had more shipping and ships using the Greenwich Meridian than the rest of the world put together (at the time). Some countries such as China use a single time zone even though their territory extends beyond the 15 degrees of longitude. The main factors that favored Greenwich as the site of the prime meridian were: Is the prime meridian in the wrong place? Each train station set its own clock making it difficult to coordinate train schedules and confusing passengers. The time zones of the United States are standardized by Congress and although the lines were drawn to avoid populated areas, sometimes they've been moved to avoid complications. Sir Sandford Fleming was one of the key players in developing a satisfactory worldwide system of keeping time. In 1764, the chronometer was invented. For example, a DAG with a start date in the US/Eastern time zone with a schedule of 0 0 * * * will run daily at 04:00 UTC during daylight savings time and at 05:00 otherwise. There were also major safety issues as many trains would share a single track and thus exact time was critical.
