This is something truly Indian. This is an Indian sundial clock on display in the Garden of Five Senses. It tells the accurate time of a place, measuring the position of the sun with respect to the longitude of the place. The Indian Standard Time (IST) is set in correspondence to the longitude : 25° 9′ 0″ N, 82° 30′ 0″ E, which passes through the city of Allahabad. However, with this sundial, one can find the exact scientific time in any place. The reason I get so fascinated with ancient Indian gadgets is the idea that people with comparatively far less resources were able to produce such marvels. I have just one thing to say for that Wow :-)
