Shanks, The American Atlas (5th edition), 20# San Diego: ACS Publications, Inc. (1991). 21# Make sure you have the errata sheet; the book is somewhat useless without it. 22# It is the source for the US and Puerto Rico entries below. 23 24# From Paul Eggert (1996-06-12): 25# Daylight Saving Time was first suggested as a joke by Benjamin Franklin 26# in his whimsical essay ``Turkey vs Eagle, McCauley is my Beagle'' (1784). 27# Not everyone is happy with the results: 28# 29# I don't really care how time is reckoned so long as there is some 30# agreement about it, but I object to being told that I am saving 31# daylight when my reason tells me that I am doing nothing of the kind. 32# I even object to the implication that I am wasting something 33# valuable if I stay in bed after the sun has risen. As an admirer 34# of moonlight I resent the bossy insistence of those who want to 35# reduce my time for enjoying it. At the back of the Daylight Saving 36# scheme I detect the bony, blue-fingered hand of Puritanism, eager 37# to push people into bed earlier, and get them up earlier, to make 38# them healthy, wealthy and wise in spite of themselves. 39# 40# -- Robertson Davies, The Diary of Samuel Marchbanks (1947), XIX, Sunday 41 42# From Arthur David Olson: 43# US Daylight Saving Time ended on the last Sunday of *October* in 1974.

402# Michigan didn't observe DST from 1968 to 1973. 403# 404# From Paul Eggert (1995-12-19): 405# Shanks writes that Michigan started using standard time on 1885 Sep 18, 406# but Howse (p 126) writes that Detroit kept 407# 408# local time until 1900 when the City Council decreed that clocks should 409# be put back twenty-eight minutes to Central Standard Time. Half the 410# city obeyed, half refused. After considerable debate, the decision 411# was rescinded and the city reverted to Sun time. A derisive offer to 412# erect a sundial in front of the city hall was referred to the 413# Committee on Sewers. Then, in 1905, Central time was adopted 414# by city vote. 415# 416# This story is too entertaining to be false, so go with Howse over Shanks. 417# 418# Most of Michigan observed DST from 1973 on, but was a bit late in 1975. 419# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER 420Rule Detroit 1948 only - Apr lastSun 2:00 1:00 D 421Rule Detroit 1948 only - Sep lastSun 2:00 0 S 422Rule Detroit 1967 only - Jun 14 2:00 1:00 D 423Rule Detroit 1967 only - Oct lastSun 2:00 0 S 424# Zone NAME GMTOFF RULES FORMAT [UNTIL] 425Zone America/Detroit -5:32:11 - LMT 1905 426 -6:00 - CST 1915 May 15 2:00 427 -5:00 - EST 1942 428 -5:00 US E%sT 1946 429 -5:00 Detroit E%sT 1973 430 -5:00 US E%sT 1975 431 -5:00 - EST 1975 Apr 27 2:00 432 -5:00 US E%sT
