 # In January 1906, several thousand cotton-mill workers rioted on the
 # outskirts of Bombay....  They were protesting the proposed abolition of
 # local time in favor of Indian Standard Time....  Journalists called this
 # dispute the "Battle of the Clocks."  It lasted nearly half a century.

+# From Paul Eggert (2017-04-20):
+# Good luck trying to nail down old timekeeping records in India.
+# "... in the nineteenth century ... Madras Observatory took its magnetic
+# measurements on Göttingen time, its meteorological measurements on Madras
+# (local) time, dropped its time ball on Greenwich (ocean navigator's) time,
+# and distributed civil (local time)." -- Bartky IR. Selling the true time:
+# 19th-century timekeeping in america. Stanford U Press (2000), 247 note 19.
+# "A more potent cause of resistance to the general adoption of the present
+# standard time lies in the fact that it is Madras time.  The citizen of
+# Bombay, proud of being 'primus in Indis' and of Calcutta, equally proud of
+# his city being the Capital of India, and - for a part of the year - the Seat
+# of the Supreme Government, alike look down on Madras, and refuse to change
+# the time they are using, for that of what they regard as a benighted
+# Presidency; while Madras, having for long given the standard time to the
+# rest of India, would resist the adoption of any other Indian standard in its
+# place." -- Oldham RD. On Time in India: a suggestion for its improvement.
+# Proceedings of the Asiatic Society of Bengal (April 1899), 49-55.
+#
+# "In 1870 ... Madras time - 'now used by the telegraph and regulated from the
+# only government observatory' - was suggested as a standard railway time,
+# first to be adopted on the Great Indian Peninsular Railway (GIPR)....
+# Calcutta, Bombay, and Karachi, were to be allowed to continue with their
+# local time for civil purposes." - Prasad R. Tracks of Change: Railways and
+# Everyday Life in Colonial India. Cambridge University Press (2016), 145.

+# This lists +052110 as Madras local time used in railways, and says that on
+# 1906-01-01 railways and telegraphs in India switched to +0530.  Some
+# municipalities retained their former time, and the time in Calcutta
+# continued to depend on whether you were at the railway station or at
+# government offices.  Government time was at +055320 (according to Shanks) or
+# at +0554 (according to the Indian Year Book).  Railway time is more
+# appropriate for our purposes, as it was better documented, it is what we do
+# elsewhere (e.g., Europe/London before 1880), and after 1906 it was
+# consistent in the region now identified by Asia/Kolkata.  So, use railway
+# time for 1870-1941.  Shanks is our only (and dubious) source for the
