Standard meridian |
| Answer» Standard time is the synchronization of clocks within a geographical area to a single standard time, rather than using solar time or a locally chosen meridian (longitude) to establish a local mean time standard.A country may have many longitudes running across it\xa0and there is a time gap of 4 minutes between each longitude.\xa0For example, the time gap between the western point of Gujarat and the easternmost point of Arunachal Pradesh has a time gap of 2 hours. So, there is a lot of confusion in the whole country. Therefore, a standard meridian should be established in each country as it is the central longitude of the whole country so that there is an equal time in all the country. | |
