Small changes are better RE: Daylight savings time -- MIDRANGE-L

I usually do the hour change right after a backup.

I recently had a situation where a shipment was made to a customer a weekearly in error, and the customer agreed to keep the shipment, provided thebilling was as if it got shipped when it was supposed to.

I was able to get the system to do this, by several manipulations,including advancing the system date to when the shipment should have beenmade, then having the billing run, so the "corrected" dates into whenreceivables due and general ledger etc. (fortunately inside the same fiscalperiod), then putting the system date back to what it should be.

The users quite happy ... which is the case any time Al Mac does some"magic" to make data come out "right" without people having to do any realwork to accomplish the goals.


I would not be surprised if my action violated SOX.

Wow! I had lots of unexpected chaos for the time frame between the two dates.

I'm in the Chicago suburbs and we're using QN0600CST: Central Standard Time.

Note: If you change QTIMZON, be sure to check your system time
afterwards; if you had the default offset of 00 hours and you change it
to -06 hours for CST, your clock may suddenly change.  In this event,
you can follow up with a CHGSYSVAL QHOUR 'nn' where nn is the right hourand is in single quotes. So, to be safe I'd advise you make any changesafter hours or when system activity is minimal.

So, what is more correct for a simple shop here in the middle of the
good ol' USA? The terms I remember being used in dealing with Daylightsavings time here have to do with what phase you're in. As in in thewinter here we say "Central Standard Time" and in the summer we would bein "Central Daylight Time".
Going by what you've told me Bruce I'd say that QN0600S would be the oneI'd want to use. Is this the option most US Central Time Zone shops usethat don't have to worry about people in other time zones using their
system?

The difference is the name.  Not all countries in the same time zone
(UTC offset of -6 for instance) may use the same abbreviations and
names.
Since these names/abbreviations can show up on panels, reports, etc it'simportant to have the name match the expectations of the country where thesystem is being used. This is one of the reasons there are so many
*TIMZON descriptions supplied with i5/OS.

Daylight savings time question.  V5R3

Other then the "Daylight Savings Time Name" what exactly is the
difference between the time zone identifiers

"QN0600S" Central Standard Time (S) - Daylight Saving Time (DST)
And
"QN0600CST" Central Standard Time (CST) - Central Daylight Time (CDT)

They both seem to have the automatic daylight savings time "Enable
Daylight Saving Time" options setup the same. What am I missing, what'sthe difference?
