Here's a proposed patch to the tz database to accommodate Venezuela's
latest plans, along with the other stuff that has been accumulated recently.

The following change affects near-future time stamps.  

* Venezuela is changing their clocks on December 9 at 03:00, instead
  of the January 1 at 00:00 that we thought.  (Thanks to John
  Stainforth for the heads-up.)


The following change affects the country database, but not the time data.

* New links America/St_Barthelemy and America/Marigot, for the
  new countries St Barthelemy and St Martin (French part).
  (Thanks to Mark Davis for this.)


The following changes affect commentary only.  

* Add a comment about Iran's readoption of DST.
  (Thanks to Roozbeh Pournader for this.)

* Fix some broken links in tz-link.htm, and remove some dead links.
  (Thanks to Bert van Heerde for this.)  Changes include:

   - Update links to calconnect, ICU.

   - Remove links to xmlDate, Austria National Metrology Institute database.

   - draft-ietf-dhc-timezone-option-04.txt is now Internet RFC 4833.

-# http://www.venezuelanalysis.com/analysis/2645:
-# The proposal ... involves turning the clock back half an hour from
-# +4.00 Greenwich Mean Time (GMT), to +4.30GMT, the time zone
-# Venezuela had until December 31, 1964, when the current time zone
-# was adopted. The change was due to take place on September 17 and
-# then on September 24, but has since been postponed until December
-# 31, to allow for compliance with international organizations, such
-# as the International Office of Weights and Measures.
+# From John Stainforth (2007-11-28):
+# ... the change for Venezuela originally expected for 2007-12-31 has
+# been brought forward to 2007-12-09.  The official announcement was
