# A writer from the Inter Tribal Council of Arizona, Inc.,
# notes in private correspondence dated 12/28/87 that "Presently, only the
# Navajo Nation participates in the Daylight Saving Time policy, due to its
# large size and location in three states." (The "only" means that other
# tribal nations don't use DST.)
# From Arthur David Olson:
# And then there's Hawaii.
# DST was observed for one day in 1933;
# Standard time was change by half an hour in 1947;
# it's always standard as of 1986.

# Indiana
#
# From Paul Eggert (1995-12-19):
# Indiana generally observes either EST all year, or CST/CDT,
# but areas near Cincinnati and Louisville use those cities' timekeeping
# and in 1969 and 1970 the whole state observed daylight time;
# and there are other exceptions as noted below.
# Shanks partitions Indiana into 345 regions, each with its own time history,
# and writes ``Even newspaper reports present contradictory information.''
# Fortunately, most of the complexity occurred before our cutoff date of 1970.
#
# Since 1970, EST-only Indiana has been like America/Indianapolis,
# with exceptions noted below for Crawford, Starke, and Switzerland counties.
# The parts of Indiana not listed below have been like America/Chicago,
# America/Louisville, or America/New_York.
#
# Other than Indianapolis, the Indiana place names are so nondescript
# that they would be ambiguous if we left them at the `America' level.
# So we reluctantly put them all in a subdirectory `America/Indiana'.
#
# Most of EST-only Indiana last observed DST in 1970.

# Michigan
#
# From Bob Devine (January 28, 1988):
# Michigan didn't observe DST from 1968 to 1973.
#
# From Paul Eggert (1995-12-19):
# Shanks writes that Michigan started using standard time on 1885 Sep 18,
# but Howse (p 126) writes that Detroit kept
#
# local time until 1900 when the City Council decreed that clocks should
# be put back twenty-eight minutes to Central Standard Time. Half the
# city obeyed, half refused. After considerable debate, the decision
# was rescinded and the city reverted to Sun time. A derisive offer to
# erect a sundial in front of the city hall was referred to the
# Committee on Sewers. Then, in 1905, Central time was adopted
# by city vote.
#
# This story is too entertaining to be false, so go with Howse over Shanks.
#
# Most of Michigan observed DST from 1973 on, but was a bit late in 1975.
