Hi,

The problem with the way IBM handled the effective date of the time zone
change, (by adding new *TIMZON objects), is that eventually they will run
out of time zones.  If you look at the format of the time zone object names
in QSYS, almost all of the characters are used.  (I would add a chart, but
it wouldn't replicate to the list.)  This was a good design, because the
names were both (mostly) obvious and meaningful. (After someone took a few
minutes to explain the format to you.)

There's basically only one additional character to handle problems like
Indiana Hawaii and Arizona (not that I have any problems with Rob or Wayne
Evans).  As time passes, and time zones morph (and both will happen [God
willing]), there will be more are more time zone changes, and we will run
out of the nine character limit for time zone changes, at which point IBM
will either have to:

o     violate their own time zone naming rules (*UGLY)
o     re-use "old" and presumably unused ones.

The proper solution (IMHO) is to modify time zone objects to have an
"effective date of change" field, with additional rules, changing this from
what is now essentially a one dimensional array to a two dimensional array.
Although this change would not have been "cheap" from an IBM effort
perspective, it would have been a significantly better enduring design.
Other issues would have been what date format is used in the time zone
itself, and how do you change that when the system value QDATFMT is
changed, but IBM does seem to be able to handle this effectively (although
I must confess that I have never changed QDATFMT for anyone! in the
remainder of the system.

Given what IBM has done, I don't think that realistically there's any going
back to a better design.  Anything you would likely do would probably break
more users than fix them:-((((((((

Just a little history:

o     The correct name is "Daylight Saving Time", not "Daylight SavingS
Time".
o     It was first proposed in 1784 by Benjamin Franklin as "Daylight
Candle Saving Time".  (This guy was no dummy.)
o     It was first adopted in 1918 to save energy during WW1, and was
repealed a year later (after the war concluded) because of rural
complaints.  (Farmers, et. all.)
o     It was re-adopted year round in 1942 to save energy during WW2,
although Michigan and Ohio didn't buy in.  Many states used "Double
Daylight Saving Time" then in the summer!  I don't have good facts on his,
but if you do, please forward them along.
o     In 1966, Congress standardized DST, but Indiana, Hawaii and Arizona
balked.
o     If you're 50 or older, you will likely remember when Richard Nixon
moved the country to DST during the Arab Oil Embargo in January 1974.  (Dem
Arabs thought they had the biggest monopoly in world, but nobody told them
that Bill Gates was coming!)
o     In 1986, it was extended from six months to seven, but I don't
remember details.
o     Effective this year, it goes to eight months, with one of the
benefits being an extra hour of light on the evening of Halloween!

Isn't that more wanted you wanted to know!

Jim,

After reading information at the link you posted, and following link after
link after link after link in typical IBM fashion, I don't really know what
is supposed to be done, if anything.  (Aside:  Does anyone else ever feel
like they're going in circles when following IBM support link?  I keep
thinking the next link will give me that Aha! Experince and I will
understand what IBM is trying to say.)

Does iNav have a problem with time zones?  Is it java within iNav that has
a
problem?  Is it java on PCs period?  Is it only if you've written
applications in java?  Is it IBM supplied 'applications' in iNav that have
a
problem?  Is it something I need to do at each PC that has iNav?  If so,
why
not an iSeries Access service pack?

I admit I am totally lost trying to determine what I am supposed to do.

No one answered my post this morning so I assume all have
either updated iSeries Navigator separately or just don't
care if it's understanding of time is unpatched (just because
it's a pc doesn't mean the Win fix fixes
it)

Enjoy the time change this weekend (some of you).

Found out that our plants in Mexico change on a different date.
