Worldwide Time Zones
In 1878, Sir Sandford Fleming (1827-1915) developed the system of worldwide time zones that we still use today. He proposed that the world be divided into 24 time zones, each separated by of longitude. He chose this figure because the Earth completes a rotation every 24 hours, and there are 360° of longitude; so the Earth rotates through 360°/24 of a circle, or 15°, every hour.
Standard Time
The local time of a place depends on the meridian of longitude that passes through it. As there are several longitudes passing through India so using them to calculate the time will create great confusion because if each place in he country followed its local time. For example it would not be possible to prepare a common railway or airlines time - table for the country. To avoid this contusion, most countries follow a standard time. The standard time for each country is usually taken as the time of the central meridian of that country.
In India the local time of the central meridian of India E is taken as the standard time for the entire country. It is called the Indian Standard Time (IST). The central meridian passes through Mirzapur near Allahabad.
