proposed tz changes for Brazil DST, Asia/Gaza, tzfile.5, and comments

It's time to update tz, as the clocks in much of Brazil do not
currently agree with what tz claims.  Here's a proposed patch that
address the following issues that have accumulated over time.

 * Update the rules for Brazil's summer of 1997-1998, thanks to Daniel
   C. Sobral <dcs at gns.com.br>.  Now the Pope is getting into the
   daylight-saving act!

 * Change Asia/Gaza to use Jordan's DST rules starting in 1996, and
   observe the Zion rules from 1940 through 1947, as suggested by Amos
   Shapir <amos at nsof.co.il>.

 * Mention size of reserved-for-future-use space in tzfile.5, as
   suggested by Denis Excoffier <Denis.Excoffier at ens.fr>.

 * The CIA no longer claims that Uzbekistan has two time zones, so remove
   commentary dismissing that claim.

 * Use comment headings that reflect the ISO country code table more
   accurately for UK/Eire, Denmark, Faeroe, Greenland, Svalbard, Jan
   Mayen, China, Taiwan, Korea (North and South), US minor outlying
   islands, and French Southern & Antarctic Lands.  This was suggested by
   Dave Skinner <dave at kirdu.jpl.nasa.gov>.  Palestine is still a special
   case; it has no ISO country code but has its own section regardless,
   as I expect it to get a country code eventually.

 * Update and correct URLs, some of which have become outdated.

I still have two big tasks in my in-box: Law's data and Olson's
suggestion for automatically maintaining last-changed times; these
will have to wait until I get more free time.

  # Palestine
+ 
+ # From Amos Shapir <amos at nsof.co.il> (1998-02-15):
+ #
+ # From 1917 until 1948-05-15, all of Palestine, including the parts now
+ # known as the Gaza Strip and the West Bank, was under British rule.
+ # Therefore the rules given for Israel for that period, apply there too.
+ # (Though I find the name "Zion" rather inappropriate -- why not just call
+ # it "Israel" or "Palestine"?)
+ #
+ # The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
+ # (except a short occupation by Israel from 1956-11 till 1957-03, but no
+ # time zone was affected then).  It was never formally annexed to Egypt,
+ # though.
+ #
+ # The rest of Palestine was under Jordanian rule at that time, formally
+ # annexed in 1950 as the West Bank (and the word "Trans" was dropped from
+ # the country's previous name of "the Hashemite Kingdom of the
+ # Trans-Jordan").  So the rules for Jordan for that time apply.  Major
+ # towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
+ # East Jerusalem.
+ #
+ # Both areas were occupied by Israel in June 1967, but not annexed (except
+ # for East Jerusalem).  They were on Israel time since then; there might
+ # have been a Military Governor's order about time zones, but I'm not aware
+ # of any (such orders may have been issued semi-annually whenever summer
+ # time was in effect, but maybe the legal aspect of time was just neglected).
+ #
+ # The Palestinian Authority was established in 1993, and got hold of most
+ # towns in the West Bank and Gaza by 1995.  I know that in order to
+ # demonstrate some manner of independence, they have been switching to
+ # summer time and back on a different schedule than Israel's, but I don't
+ # know when this was started, or what algorithm is used (most likely the
+ # Jordanian one).
+ #
+ # To summarize, the table should probably look something like that:
+ #
+ # Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
+ # ------------+-----------+-----------+-----------+-----------
+ # Israel      | Zion      | Zion      | Zion      | Zion
+ # West bank   | Zion      | Jordan    | Zion      | Jordan
+ # Gaza        | Zion      | Egypt     | Zion      | Jordan
+ #
+ # I guess more info may be available from the PA's web page (if/when they
+ # have one).
+ 
+ # From Paul Eggert (1998-02-25):
+ # Shanks writes that Gaza did not observe DST until 1957, but we'll go
+ # with Shapir and assume that it observed DST from 1940 through 1947,
+ # and that it used Jordanian rules starting in 1996.
+ # We don't yet need a separate entry for the West Bank, since
+ # the only differences between it and Gaza that we know about
+ # occurred before our cutoff date of 1970.
+ # However, as we get more information, we may need to add entries
+ # for parts of the West Bank as they transitioned from Israel's rules
+ # to Palestine's rules.  If you have more info about this, please
+ # send it to tz at elsie.nci.nih.gov for incorporation into future editions.
+ 
  # These rules for Egypt are stolen from the `africa' file.
