Solution
Instructions:
- Give introduction.
- Explain the Answer
Solution:
Indian Standard Time (IST) represents the time observed throughout India.
IST is calculated on the basis of 82.5o E longitude which is just west of the town of Mirzapur, near Allahabad in the state of Uttar Pradesh
Let’s understand it through an example.
In India,
Arunachal Pradesh = 97oE, Gujarat = 67oE
97o – 67o = 30o
The distance between the two states is 30o
If the sun covers 1o in 4 mins
Then, 30o x 4 mins = 120 mins or 2hrs
The local time difference between Arunachal Pradesh and Gujarat is 2hrs.
We do not follow local time because it will lead to confusion and difficulty in maintaining train schedules, flight schedules, TV show timings, etc.
Therefore, to synchronize the time of the whole country, we use a standard meridian. The standard meridian of India is at 82o 30’
