Na time zone map

In the United States, time is divided into nine standard time zones covering the states, territories and other US possessions, with most of the country observing daylight saving time DST for approximately the spring, summer, and fall months. The time zone boundaries and DST observance are regulated by the Department of Transportation , but no single map of those existed until the agency announced intentions to make one in September The clocks run by these services are kept synchronized with each other as well as with those of other international timekeeping organizations. It is the combination of the time zone and daylight saving rules, along with the timekeeping services, which determines the legal civil time for any U. Before the adoption of four standard time zones for the continental United States, many towns and cities set their clocks to noon when the sun passed their local meridian , pre-corrected for the equation of time on the date of observation, to form local mean solar time. Noon occurred at different times but time differences between distant locations were barely noticeable prior to the 19th century because of long travel times and the lack of long-distance instant communications prior to the development of the telegraph. The use of local solar time became increasingly awkward as railways and telecommunications improved. Each train station set its own clock making it difficult to coordinate train schedules and confusing passengers. Time calculation became a serious problem for people traveling by train sometimes hundreds of miles in a day , according to the Library of Congress. Train drivers must recalculate their own clocks in order to know departure time. Every city in the United States used a different time standard so there were more than local sun times to choose from. Time zones were therefore a compromise, relaxing the complex geographic dependence while still allowing local time to be approximate with mean solar time. Railroad managers tried to address the problem by establishing railroad time zones, but this was only a partial solution to the problem.
