Daylight saving time
I found a nice page about daylight saving time that I want to share:
http://timeanddate.com/time/aboutdst.html
Here are some fun quotes from the page:
"Sometimes DST is used for longer periods than just one summer, as in the
United States during World War II. From 3 Feb 1942 to 30 Sep 1945 most of
United States had DST all year, it was called "War Time"."
"many countries change the transition days/principles every year because
of special happenings or conditions that has happened or will happen."
Also notice the current list of DST changes for this fall 2004:
http://timeanddate.com/time/dst2004b.html
I can understand why they did not try to formalize that in the sql spec.
ps. This letter does not mean that I think it's bad to handle time zone
names, just that it's even more difficult then I first thought.

This is why we are being careful not to introduce any local changes into
the zic database. We can just drop in upstream changes from time to
time; or users can drop in copies if they need an update and it's the
wrong time of the PG release cycle.

Dear Dennis and my Fellowmen,
How would you like to evaluate a new simplified time zone system for
the world and in decimal? This is found in
