Below find proposed changes to the time zone package; the executive summary: * leapseconds Update notice from IERS (change to commentary only) * northamerica Replace Juneau with Juneau, Sitka, and Metlakatla. * southamerica Delay end of DST in 2011 until first Sunday in April. * tz-art.htm Add material on episode of "Outsourced." * zone.tab Replace Juneau with Juneau, Sitka, and Metlakatla. These change do affect current time stamps in Metlakatla and immiment time stamps in Chile. I'm waiting on making changes to Russia until we learn whether or not their new, year-round time will be called standard time; we'll see what happens at the end of this month. Since the Chile change is being made on short notice, I'll update the ftp versions on 2011-03-07 if no problems are found. --ado diff -r -c old/leapseconds new/leapseconds *** old/leapseconds Thu Dec 16 12:24:20 2010 --- new/leapseconds Mon Feb 14 09:30:33 2011 *************** *** 1,5 **** # <pre> ! # @(#)leapseconds 8.10 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)leapseconds 8.11 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 56,68 **** # SERVICE DE LA ROTATION TERRESTRE # OBSERVATOIRE DE PARIS # 61, Av. de l'Observatoire 75014 PARIS (France) ! # Tel. : 33 (0) 1 40 51 22 26 # FAX : 33 (0) 1 40 51 22 91 # Internet : services.iers@obspm.fr # ! # Paris, 14 July 2010 # ! # Bulletin C 40 # # To authorities responsible # for the measurement and --- 56,68 ---- # SERVICE DE LA ROTATION TERRESTRE # OBSERVATOIRE DE PARIS # 61, Av. de l'Observatoire 75014 PARIS (France) ! # Tel. : 33 (0) 1 40 51 22 29 # FAX : 33 (0) 1 40 51 22 91 # Internet : services.iers@obspm.fr # ! # Paris, 2 February 2011 # ! # Bulletin C 41 # # To authorities responsible # for the measurement and *************** *** 70,78 **** # # INFORMATION ON UTC - TAI # ! # NO positive leap second will be introduced at the end of December 2010. # The difference between Coordinated Universal Time UTC and the ! # International Atomic Time TAI is : # # from 2009 January 1, 0h UTC, until further notice : UTC-TAI = -34 s # --- 70,78 ---- # # INFORMATION ON UTC - TAI # ! # NO positive leap second will be introduced at the end of June 2011. # The difference between Coordinated Universal Time UTC and the ! # International Atomic Time TAI is : # # from 2009 January 1, 0h UTC, until further notice : UTC-TAI = -34 s # *************** *** 82,87 **** # will be no time step at the next possible date. # # Daniel GAMBIS ! # Director ! # Earth Orientation Center of IERS # Observatoire de Paris, France --- 82,87 ---- # will be no time step at the next possible date. # # Daniel GAMBIS ! # Head ! # Earth Orientation Center of the IERS # Observatoire de Paris, France diff -r -c old/northamerica new/northamerica *** old/northamerica Wed Jan 26 17:13:48 2011 --- new/northamerica Wed Feb 9 14:00:33 2011 *************** *** 1,5 **** # <pre> ! # @(#)northamerica 8.40 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)northamerica 8.41 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 426,431 **** --- 426,473 ---- # were nearby inhabitants in some cases and for our purposes perhaps # it's best to simply use the official transition. # + + # From Steve Ferguson (2011-01-31): + # The author lives in Alaska and many of the references listed are only + # available to Alaskan residents. + # + # <a href="http://www.alaskahistoricalsociety.org/index.cfm?section=discover%20alaska&page=Glimpses%20of%20the%20Past&viewpost=2&ContentId=98"> + # http://www.alaskahistoricalsociety.org/index.cfm?section=discover%20alaska&p... + # </a> + + # From Arthur David Olson (2011-02-01): + # Here's database-relevant material from the 2001 "Alaska History" article: + # + # On September 20 [1979]...DOT...officials decreed that on April 27, + # 1980, Juneau and other nearby communities would move to Yukon Time. + # Sitka, Petersburg, Wrangell, and Ketchikan, however, would remain on + # Pacific Time. + # + # ...on September 22, 1980, DOT Secretary Neil E.
