'''Madras Time''' was a [[time zone]] established in 1802 by [[John Goldingham]], the first official astronomer of the [[British East India Company]] in [[India]] when he determined the longitude of [[Madras]] as 5 hours, 21 minutes and 14 seconds ahead of [[Greenwich Mean Time]].<ref>{{Cite journal|editor=William Nicholson|title=Eclipses of the Satellites of Jupiter, observed by John Goldingham and under his Superintendence, at Madras, in the East Indies|journal=A Journal of Natural Philosophy, Chemistry, and the Arts|publisher=Stratford, Crown Court and Temple Bar|location=London|date=1809|volume=22|pages=153–156|url=https://books.google.com/books?id=xJAOjlQ6TNMC&q=madras+time++goldingham+1802&pg=PA153}}</ref> It has been described as 8 minutes and 46 seconds from [[UTC+05:30]]<ref>{{Cite journal|title=On Time in India|journal=Proceedings of the Asiatic Society of Bengal|publisher=Asiatic Society of Bengal|location=Calcutta|date=April 1899|pages=49–55|url=https://books.google.com/books?id=kIIbAQAAIAAJ&q=%22madras+time%22&pg=PA51}}</ref> and 32 minutes and 6 seconds behind [[Calcutta Time]]<ref>{{Cite journal|title=On the Introduction of a Standard Time for India|journal=Proceedings of the Asiatic Society of Bengal|publisher=Asiatic Society of Bengal|location=Calcutta|date=June 1899|pages=62–66|url=https://books.google.com/books?id=kIIbAQAAIAAJ&q=%22Calcutta+time%22+%22madras+time%22&pg=PA63}}</ref> which puts it at ([[UTC+05:00|UTC+05:21:14]]). Before India's independence, it was the closest precursor to [[Indian Standard Time]] which is derived from the location of the observatory at 82.5°E longitude in Shankargarh [[Allahabad]] in [[Uttar Pradesh]].<ref name="Princely states">{{cite web|url=http://www.irfca.org/faq/faq-misc.html |title=Odds and Ends |access-date=2013-06-03 |publisher=Indian Railways Fan Club}}</ref><br />

After [[Bombay Time]] and [[Calcutta Time]] were set up as the two official time zones of [[British India]] in 1884, railway companies in India began to use Madras time as an intermediate time zone between the two zones. This led to Madras time also being known as "[[Railway time#India|Railway time of India]]".<ref name="Princely states"/><br />
