Question

The sun rises two hours earlier in arunachal pradesh as compared to gujrat but watch shows the same time .why

Answer 1

The Indian Standard Time is applicable only for a particular longitude and the time is fixed with respect to this longitude only.Hence the sunrise and the sunset time pertaining to that particular longitude will be different for other longitudes.As India covers many longitudes(east-west),places lying on other longitudes within the country,will therefore have different sunrise and sunset time.

Answer 2

The clocks in Arunachal Pradesh and Gujrat are set to the same time zone, but Arunachal Pradesh and Gujrat are in different longitudes, and Arunachal Pradesh is 30 degrees of longitude east of Gujrat.
