# 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

# 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
