|
|
# 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.

|
#
|
|
|
|
|
# Other than Indianapolis, the Indiana place names are so nondescript
|

|
# that they would be ambiguous if we left them at the `America' level.

# From W. Jones (jones@skdad.usask.ca) (November 6, 1992):
|
|
|
|
|
# The. . .below is based on information I got from our law library, the
|
|
|
|
|
# provincial archives, and the provincial Community Services department.
|
|
|
|
|
# A precise history would require digging through newspaper archives, and

# since you didn't say what you wanted, I didn't bother.

|
|
|
# Saskatchewan is split by a time zone meridian (105W) and over the years
|
|
|
|
|
# the boundary became pretty ragged as communities near it reevaluated
|
|
|
|
|
# their affiliations in one direction or the other. In 1965 a provincial
|
|
|
|
|
# referendum favoured legislating common time practices.

|
|
|
# On 15 April 1966 the Time Act (c. T-14, Revised Statutes of
|
|
|
|
|
# Saskatchewan 1978) was proclaimed, and established that the eastern
|
|
|
|
|
# part of Saskatchewan would use CST year round, that districts in
|
|
|
|
|
# northwest Saskatchewan would by default follow CST but could opt to
|
|
|
|
|
# follow Mountain Time rules (thus 1 hour difference in the winter and
|
|
|
|
|
# zero in the summer), and that districts in southwest Saskatchewan would
|
|
|
|
|
# by default follow MT but could opt to follow CST.

# It took a few years for the dust to settle (I know one story of a town
|
|
|
|
|
# on one time zone having its school in another, such that a mom had to
|
|
|
|

# serve her family lunch in two shifts), but presently it seems that only
|
|
|
|
|
# a few towns on the border with Alberta (e.g. Lloydminster) follow MT

# rules any more; all other districts appear to have used CST year round

# Here's how I would summarize things. Establish a "Saskatchewan" CST
|
|
|
|
|
# time zone, and note that it officially exists as of 15 April 1966. Any
|
|
|
|
|
# current exceptions can put themselves in the "Mountain" zone, since
|
|
|
|
|
# those are the rules they follow. Any past exceptions can be forgotten,
|
|
|
|
|
# since that's what those who live here have done.

# From Arthur David Olson (November 21, 1992):

# From Guy Harris:
|
|
|
|
|
# Rules are from the Official Airline Guide, Worldwide Edition, for 1987.
|
|
|
|
|
# Rules prior to 1987 are unknown.
|
|
|
|
|
# The comments in the OAG say "Only Ensenada, Mexicale, San Felipe and Tijuana
|
|
|
|
|
# observe DST." This is presumably Baja California Norte, above 28th parallel,
|
1996-01-09 01:36:35 +03:00
|
|
|
# as listed there; [there is also] "Baja California Sur and N. Pacific
|
1993-03-21 12:45:37 +03:00
|
|
|
# Coast (States of Sinaloa and Sonora)."
|
|
|
|
|
|
|
|
|
|
# From Bob Devine (January 28, 1988):
|
|
|
|
|
# The Federal District (where Mexico City is) has observed [DST] several
|
|
|
|
|
# times but not recently.

|
|
|
# I don't where to drawn the line in the North Baja area. 28th latitude
|
|
|
|
|
# sounds good -- but it may be higher (how far [d]o radio stations from
|
|
|
|
|
# San Diego affect culture?).

|
# The dates of DST probably go back to 1981. The rules are the same as
|
|
|
|
|
# US's. This is going to be a headache for US presidential electi[o]n years!
|
|

|
|
|
|
|
|
|
# From Arthur David Olson (February 13, 1988)
|
