What I find interesting is that India is 9 1/2 hours ahead of the east coast of the U.S. Yep, there's that 1/2 hour thrown in there. I can't remember why and I'm too lazy right now to look it up.
Here is a time zone converter for those interested. Of course, from the flat earth viewpoint, we are all in the same time zone as everywhere would have high noon at the same time.
India's time zone is UTC/GMT (Coordinated Universal Time/Greenwich Mean Time) +5.5 hours. It's referred to as Indian Standard Time (IST). What's unusual is that there is only one time zone across the whole of India. The time zone is calculated according to the longitude of 82.5° E. at Shankargarh Fort in Mirzapur (in the Allahabad district of Uttar Pradesh), which was picked as the central meridian for India. It's also important to note is that Daylight Saving Time doesn't operate in India. Time Differences Between Various Countries. In general, without taking into account Daylight Saving Time, the time in India is 12.5 hours ahead of the west coast of the USA (Los Angeles, San Fransisco, San Diego), 9.5 hours ahead of the east coast of the USA (New York, Florida), 5.5 hours ahead of the UK, and 4.5 hours behind Australia (Melbourne, Sydney, Brisbane). History of India's Time Zone Time zones were officially established in India in 1884, during British rule. Two time zones were used -- Bombay Time and Calcutta Time -- due to the importance of these cities as commercial and economic centers. In addition, Madras Time (set up by astronomer John Goldingham in 1802) was followed by many railway companies. IST was introduced on January 1,1906. However, Bombay Time and Calcutta Time continued to be maintained as separate time zones until 1955 and 1948 respectfully, after India's Independence. Although India currently doesn't observe Daylight Saving Time, it did briefly exist during the Sino-Indian War in 1962 and the India-Pakistan Wars in 1965 and 1971, in order to reduce civilian energy consumption. https://www.tripsavvy.com/what-is-the-india-time-zone-1539421
