proposed tz patches for Indiana, New Brunswick, Gaza, etc.

Paul Eggert eggert at CS.UCLA.EDU
Fri Jan 20 22:59:51 UTC 2006 

Here are some proposed changes to the tz database reflecting the
recent flurry of email about Indiana, along with other news about New
Brunswick and Gaza, and other less-important changes that I've been
saving up.

Changes to the tz data.

* Create a new zone America/Indiana/Petersburg for Pike County,
  Indiana, which moved from central to eastern time in 1977.
  Thanks to Gwillim Law for the heads-up.

* Adjust America/Indiana/Petersburg and America/Indiana/Knox, since
  Pike and Starke Counties will switch to CST in April.  Create a new
  Zone America/Indiana/Vincennes for Daviess, Dubois, Knox, Martin,
  Perry, and Pulaski Counties, Indiana, which will also switch.
  Thanks to Deborah Goldsmith for the DOT news.

* Create a new zone America/Moncton for New Brunswick, which recently
  announced that it will follow the new US rules in 2007.  New
  Brunswick switches at 00:01, not 02:00, so it needs a separate zone.

* In October 2005 Gaza switched at 02:00, not 01:00.  Thanks to
  Steffen Thorsen for this info.

  
Commentary fixes only.

* Note that we don't have the data yet for the 2003-10-26 time zone
  change in Morton and Sioux Counties, North Dakota.  Thanks to
  Gwillim Law for the heads-up.

* Identify which Michigan counties were affected by the 1973 change.
  Thanks to Gwillim Law for the info.

* Clinton and Russell Counties, Kentucky, were incorrectly referred to
  in a comment.
  

Minor changes to rules that don't affect behavior.

* Sort the Halifax rules by date, and use the same tabbing scheme as
  elsewhere.

  
Fixes to the web page.

* Mention the proposed IANA Time Zone Registry.

* Mention iCalendar Basic.

* Mention TZInfo, a new Ruby-based tz compiler.

* Update references to Indiana, to reflect the recent changes.

* Add a reference to Shanks's new edition (not yet available).

* Add a reference to Steve Allen's fine Time Scales web page.

* Add a reference to LeapSecond.com.

* Mention the XML schema for date and time formats, and add a reference
  to Date & Time Formats on the Web.

* Update URLs to reflect moved web pages.
