Indian Standard Time is calculated on the basis of 82.5° E longitude, which is just west of the town of Mirzapur, near Allahabad in the state of Uttar Pradesh. The longitude difference between Mirzapur and the United Kingdom's Royal Observatory at Greenwich translates to an exact time difference of 5 hours 30 minutes. Local time is calculated from a clock tower at the Allahabad Observatory (25°09′N 82°30′E / 25.15, 82.5) though the official time-keeping devices are entrusted to the National Physical Laboratory, in New Delhi.

Why is ist 5.30 hours ahead of gmt in sums?
The original time zone for India was determined in 1802, by The East India Company, from their base in Chennai (then Madras). The longitude, 80 deg 16 min puts the exact time as GMT + 5 hours 21 minutes and this was rounded to the nearest half hour. Following independence, the main observatory was moved to Shankargarh near Allahabad, which is located at longitude 82.5 deg E which puts it at GMT + 5:30 exactly.
