Mirzapur is situated on this longitude reference line. Time zones, the strict observance of time zones by countries and territories minimizes their differences because it is convenient for areas of close commercial or other communication to keep the same time.

History Of IST

After independence in 1947, our central government established IST, i.e. Indian Standard Time or Indian Standard Time. The government established IST as the official time for the entire country. It is worth noting that Kolkata and Mumbai retained their local time, known as Kolkata Time and Mumbai Time, respectively, till 1948 and 1955. The central observatory was shifted from Chennai to a location at Shergarh Fort in Prayagraj district so that it could be closer to UTC+05:30. Daylight Saving Time (DST) was briefly used during the Sino-Indian War of 1962 and the Indo-Pakistani War of 1962 and 1971. IST stands for Indian Standard Time. It is taken as it passes through almost all the centers of India. Not only this, the national All India Radio and Doordarshan television network broadcasts accurate timings to tell people the correct timings. Even mobile and telephone companies relay the exact time. The most popular way nowadays to get time is GPS – it is fast becoming popular among the youth. The complete form of GPS is Global Positioning System.

Advantages Of Using Indian Standard Time (Ist):

  • Standardization: IST provides a standardized time for the entire Indian subcontinent, making it easier for people to coordinate and schedule activities, both nationally and internationally.

  • Improved Communication: Having a standardized time across a large region like India helps improve communication and reduces the chance of misunderstandings and confusion caused by time differences.

  • Ease of Use: IST is simple and easy to understand, as it is only 5 hours and 30 minutes ahead of GMT. This makes it convenient for people who are traveling within the region, as they do not have to make significant adjustments to their schedules.

  • Facilitation of Business: IST helps facilitate business activities, both domestically and internationally, as companies can schedule meetings, conference calls, and other events with ease.

Disadvantages Of Using Indian Standard Time (Ist):

  • Confusion with Other Time Zones: IST can cause confusion with other time zones, particularly in areas near the borders of neighboring countries that have different time standards.

  • Impact on Sunrise and Sunset: The use of IST can have an impact on the perception of sunrise and sunset, as it can be difficult for people to adjust to the 5 hours and 30 minute time difference.

  • Conflicts with Local Traditions: In some parts of India, local traditions may dictate the use of a different time standard, leading to confusion and potential conflicts between local and national time practices.

  • Difficulty for People Living Near Borders: People living near the borders of neighboring countries that have different time standards may experience difficulty adjusting to the time differences and the impact it has on their daily routines.

Difference Between IST and GMT

IST stands for Indian Standard Time, while GMT stands for Greenwich Mean Time. GMT is a time standard that is often used as a reference time, as it is the time at the Prime Meridian, which is the line of longitude defined to be 0 degrees and runs from the North Pole to the South Pole. On the other hand, IST is the time in the Indian subcontinent and is 5 hours and 30 minutes ahead of GMT.

In other words, if it is 12:00 GMT, it would be 5:30 PM in IST. Both GMT and IST are used as time standards in different regions and are used for different purposes, with GMT being more commonly used as a reference time, while IST is the standard time in India and the surrounding countries.
