Automatic Mac OS X Daylight savings time switch doesn't work for some cities under Mac OS X 10.3.9
MacFixIt reader Scott Davis reports an issue where a Mac OS X 10.3.9 system set to automatically synchronize with Apple's time servers failed to recognize the recent daylight savings time switch for specific cities.
Scott writes:
"If you have Mac OS 10.3.9 and live in Indiana, Apple's not updated the time server to observe daylight-saving time.
"There was a knowledge base article on the change, but it was vague, recommending setting a selection on an Eastern time zone city,.
"Indianapolis, of course, is such a city.
"Also, some discussions in the Apple support forums were also stated that the change should happen automatically. It did not.
"Solution: Choose Detroit."
If you experienced a similar issue, please let us know.

"Updated the rules for time zones and Daylight Savings Time to conform to
changes in the law for the United States, Australia, and other locations, for
2006 and later."
It worked OK in Australia....

iMac G4 with 10.3.9 - System Time is based on Indianapolis and was NOT automatically adjusted for DST.
the time servers only sync to UTC and the actual local time is deduced from
timezone tables kept on the client.
Mac OS 9 had a checkbox to manually indicate DST, but Mac OS X doesn't. In
Brazil, where I live, DST start and end times are often changed by the
government, often only a week or two before, so Mac OS X's tables are often
wrong. I filed a bug on this years ago and it hasn't been closed yet...
Another bug has, at least, been resolved in Tiger. In Panther and older systems
there were two timezone/DST tables, the one in /usr/share/zoneinfo and
another one hardcoded into Carbon, and referred to by older APIs.
update any other versions.
Our carpetbagger governor, Mitch Daniels, convinced the state that we would
reap tremendous economic benefit from changing our clocks to match the
eastern timezone. Of course that's a bunch of male bovine excrement.
The real reason was to match Indianapolis time with the New York stock
market
so the insurance and stock traders - who give money primarily to Mitch's
party -
don't have to get up an hour earlier in the summertime.
The majority of us Indiana folks didn't care about changing our clocks. Here
again, we have an example of the rich getting what they want over the wishes
of
the majority. Such is life in the republican states of america.
Please. I hope you're just joking. The responses to this situation are the very
reason Indiana went on Daylight Saving Time: nobody outside of Indiana knew
what time we were on. Half the year we were on New York time and half on
Chicago. Eventually people will remember most of Indiana is in the Eastern Time
Zone. Personally, I think all of Indiana should have gone to Central Time. But
that's just me. I get up early in the morning and it's still dark an hour after
breakfast (no, I'm not a farmer; I'm a computer consultant).
God's Time -- no kidding). These rules have changed over the years and in
various localities in Indiana...check your local town paper. I'm from neighboring
Ohio and could never figure it out.
And to make life much more interesting, several counties applied to the Feds to
switch time zones, and some of those were allowed to. Now two of the latter
want to switch back.
Anybody know a source of USB sundials? ;-)
But remember this is the last year for the US to be on the current Daylight Saving time rule. Next year the new Daylight Saving rule which was passed as part of the energy act the start time the second week of March and ends first Sunday in November. For example for 2007 March 11 will start the Daylight Savings Time and ends on November 4, 2007.
Computer hardware and software manufactures will have fun getting all of patches for this.
Y2K all over again...

(10 Comments)based. (Indiana has always been screwed up. Crazy Hoosiers.)
10.3.9 will *not* update correctly because the fix from Apple only applies to
10.4, not 10.3.x. Update from 10.3.9 to 10.4.5 or higher to fix this. I had a
problem with one 10.3.9 PPC Mac and 10.4.5 solved its problem. Existing
10.4.5 Macs already worked OK and still do with 10.4.6.
