proposed time zone package changes (Chile, Alaska, et al.)

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.

+ # 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+ # ...on September 22, 1980, DOT Secretary Neil E. Goldschmidt rescinded the
+ # Department's September 1979 decision. Juneau and other communities in
+ # northern Southeast reverted to Pacific Time on October 26.
+ #
+ # On October 28 [1983]...the Metlakatla Indian Community Council voted
+ # unanimously to keep the reservation on Pacific Time.
+ #
+ # According to DOT official Joanne Petrie, Indian reservations are not
+ # bound to follow time zones imposed by neighboring jurisdictions.
+ #
+ # (The last is consistent with how the database now handles the Navajo
+ # Nation.)
+ 
+ # From Arthur David Olson (2011-02-09):
+ # I just spoke by phone with a staff member at the Metlakatla Indian
+ # Community office (using contact information available at
+ # <a href="http://www.commerce.state.ak.us/dca/commdb/CIS.cfm?Comm_Boro_name=Metlakatla">
+ # http://www.commerce.state.ak.us/dca/commdb/CIS.cfm?Comm_Boro_name=Metlakatla
+ # </a>).
+ # It's shortly after 1:00 here on the east coast of the United States;
+ # the staffer said it was shortly after 10:00 there. When I asked whether
+ # that meant they were on Pacific time, they said no--they were on their
+ # own time. I asked about daylight saving; they said it wasn't used. I
+ # did not inquire about practices in the past.
