Time zone changes from version 2006d1 to 2006d2:
Date : Thursday April 27, 2006 0:30 CDT
File : 2006d2.txt

Perhaps I'm jumping the gun this time before the dust settles,
but several sources say Nicaragua will apply DST next Sunday, as
"predicted" in versions 2006b1.txt and 2006b3.txt, as they did
last year, apparently because of the rising oil prices.
The articles

are talking about this. I have not found an official decree, nor
any web page that says exactly when this DST will end in Nicaragua.
In lack of better I put the rule as Last Sunday of April at 2:00
(confirmed) till Last Sunday of August at 2:00 (guessed).

* Both Philippines and El Salvador are apparently considering to
implement DST this year, here are some links:

Since we have no confirmation of these, no changes are made in
the data yet.

* Wisconsin apparently has started DST one hour early, as an ongoing
practice for many years behind, according to Larry M. Smith, who quotes
this document:

Thanks to Larry for this info! I have changed the "USA - Wisconsin" 
entries in WTE to start at 1:00 instead of at 2:00.
