Gmt Vs Ist: What’s the Difference?

If you’re planning a trip to another timezone, you might be wondering what the difference is between GMT and IST. In this article, we’ll explain the key differences and when you might want to use each.

What is GMT?

GMT is the time zone that corresponds to Coordinated Universal Time (UTC). It is UTC+0. For most of the world, GMT is what time is displayed on a sundial or clock.

In October 1884, at the International Meridian Conference in Washington, D.C., delegates from 29 countries adopted a proposal to create a universal time standard. The new time standard was to be based on the mean solar day, which was then thought to be about 24 hours long.

The first step was to find a common starting point for all clocks and calendars. GMT was decided upon as the time standard because it was close to the mean solar day. GMT was set equal to 0 hours at noon on October 15, 1904, so that all countries would be in sync.

Today, most of the world uses GMT except for some parts of Africa, Antarctica, and some parts of China that use Beijing Standard Time. Occasionally, an area will switch to GMT due to political reasons rather than using the mean solar day as the basis for timekeeping.

What is IST?

Gmt is Greenwich Mean Time, while Ist is Indian Standard Time. IST is 5 hours behind GMT.

The main difference between GMT and IST is that GMT is based on the mean sun time, while IST is based on the UTC time zone.

This means that IST changes depending on where in the world you are. For most of India and some parts of Southeast Asia, IST is 10 hours behind GMT.

What are the Differences Between GMT and IST?

GMT is the time zone that is used in most of the world. It is based on the Greenwich Mean Time ( GMT ) which is UTC+0. Hours in GMT are offset from UTC by one hour. For example, 3pm in GMT is 2pm in UTC.

IST, on the other hand, is the Indian Standard Time which is UTC+5 hours. Hours in IST are offset from UTC by 5 hours. So, 9pm in IST would be 8pm in UTC.

There are a few other minor differences between GMT and IST, but they are not worth getting into here.
