![]() ![]() Thus, there exists only one standard time in a country having comparatively less longitudinal (east-west) extent.ģ. If the difference between the local time at the extreme east and west longitude passing through a country is less than one or two hours, one standard time is considered for a country. The local time at the longitude passing through the middle of a country/ place is generally considered as a standard time of that country/place.Ģ. How is the standard time of a place determined?ġ. Therefore, if it is 12 noon at 60° E longitude, then it would be 6 a.m. Longitudes lying to the east of any longitude are ahead of the time of that longitude while those lying to the west are behind.Ĥ. (The difference of 60 degrees between 0° and 60° E + the difference of 30 degrees between 0° and 30° W = 90 degrees.)ģ. The difference between 60° E longitude and 30° W longitude will be of 90 degrees. If it is 12 noon at 60° E longitude, then explain what would be the time at 30° W longitude.ġ. ![]() Therefore, for synchronizing the routine activities in the country, Canada has 6 different standard times. Therefore, it is not practically helpful to consider single standard time in Canada. The difference between the local time at extreme east and west longitude passing through Canada is of 352 minutes i.e.Thus, the difference between the extreme east and west longitude passing through Canada is of 88 degrees.The longitudinal extent of Canada is between 52☃7′ W and 141° W.Therefore, the standard time of India has been decided by the local time at 82☃0’E longitude. The difference between the local time at 82☃0’E longitude and the local time at the extreme east and west longitude passing through India is not more than one hour.With respect to the longitudinal extent, 82☃0’E longitude passes through the middle of India.The standard time of India has been decided by the local time at 82☃0′ E longitude. For an international coordination, it is essential to bring compatibility between the standard times of various countries in the world.įor this purpose, the local time at Greenwich is considered to be the International Standard Time.0° longitude passes through Greenwich, England.The International Standard Time has been decided according to 0° longitude.The local time at Greenwich is considered to be the International Standard Time. In this way, the local time is decided by the noontime. This noontime is considered as local time of that longitude. During the rotation of the earth, when a particular longitude comes exactly in front of the sun, it is considered as noontime (12 noon) on that longitude. The time of a particular place as decided by the overhead position of the sun in the sky is considered as the local time of that place.ģ. When at a particular place, the sun reaches the maximum height in the sky it is assumed that almost half of the daytime is over and this time is considered 12 noon.Ģ. The local time is decided by the noontime.ġ. Give geographical reasons for the following: The difference between the local time of any two consecutive longitudes is ……………. ![]() (d) changes need to be made according to International Date Line. (c) the difference in standard times of both the places should be known (b) the difference in degrees of their longitudes should be known (a) the noon time at both the places should be known To calculate the difference between the local times of any two places on the earth, …………. The earth requires 24 hours for one rotation.
