Offset

The GMT offset of the Calcutta time as stated now in the article, 5 hours 30 minutes 21 seconds, must be wrong as this would be only 21 seconds apart from the contemporary IST (although IST is supposed to be in-between of the historical Bombay and Calcutta times). Going by the longitute of Kolkata one would assume that the historical Calcutta Time offset would be something near +5 hours 53 minutes, but currently I am unable to find the correct information.

Putting a ~~strike through the wrong information~~ in the article and hope someone will find the correct information soon. --94.194.213.6 (talk) 14:13, 17 November 2012 (UTC)[reply]

My "strikethrough" has been reverted now by another editor. Nevertheless, the correctness of the Calcutta time GMT offset has not been established as the "sources" quoted do not support it at all. --82.144.227.18 (talk) 16:32, 31 December 2012 (UTC)[reply]

Madras time was the intermediate "railway time" between Bombay Time and Calcutta Time and is, in that sense, the precursor to Indian Standard Time. [1]. 24.151.116.25 (talk) 21:53, 3 June 2013 (UTC)[reply]
