In the courtyard of the historic Royal Greenwich Observatory, a brass strip and a laser beam symbolize the zero meridian. Previously, numerous coordinate systems competed with each other. Only with this worldwide uniform regulation did the coordinates we know today exist. When the date line was established in a preferably uninhabited area between Asia and America, the zero meridian was established on the opposite side of the globe in Greenwich. Each section of 15° corresponded to one hour, which, at least in theory, resulted in 24 uniform time zones.
It was not until 1884 that a globally uniform time system was agreed upon, dividing the globe into 24 equal-sized areas according to their longitudes. One of the best known was already based on the Greenwich meridian. Origin of the Greenwich Mean Time During seafaring times, there were different zero meridians and systems for position calculation depending on the nation. GMT is a time zone used in some European and African countries, while UTC is a time standard that is the basis for civil time and time zones worldwide. In practice, GMT and UTC share the same time on a clock, which can cause them to be interchanged or confused.
Saint Helena, Ascension and Tristan da Cunha London uses Greenwich Mean Time (GMT) during standard time and British Summer Time (BST) during Daylight Saving Time (DST), or summer time.
