Similarities between gujrat and Arunachal Pradesh
The reason for time difference between Gujarat and Arunachal Pradesh is of 2 hours as they both lie on different longitudes.
longitudes have a difference of 4 minutes between each other so if we calculate all the time differences of the longitudes between Gujarat and Arunachal Pradesh , the difference is about 120 minutes (2 hours).
To make it more clear,
If Arunachal Pradesh and Gujarat are to keep the local time of its own meridian (position on the globe) then travelers travelling between the two states of India will have to keep changing their watches if they wanted to keep their appointments. This becomes impracticable and very problematic.
To avoid these difficulties, a system of standard time called “Indian Standard Time” is observed. The time along the Central Meridian of India i.e. 82 32’ E passing through Mirzapur (in Uttar Pradesh) is taken as the standard time for the whole country. This enables the entire country to maintain a same time on the watch irrespective of the position of the Sun over any state or location in the country.
