Re: QTIMZON Question

Jim,
Exactly. Using Windows as a reference as to how an OS should do something
is whacked.
The UTC offset never changes in Windows before or after the time change.
You're either just supposed to know this, or know how to twist the secret
decoder ring to figure out where Windows stores this. Someone on this list
told me years ago. I forget.

that Windows displays UTC offset differently than IBM i - this is a
surprise?

- btw IBM Linux/Unix same as IBM i and <guess> Mainframe s well
most, but not all generic google requests about UTC offset referenced
Windoze docs, but some were ibm i (probably from my recent specific
requests

IBM i help text specifically says the offset displayed is adjusted for
daylight savings. I can find no Windoze doc saying the same.

Offset
Contains the time difference between this time zone and Coordinated
Universal Time (UTC), specified in hours and minutes. A negative
difference indicates that the time zone is west of UTC and a
positive difference indicates that the time zone is east of UTC.
This is the offset that is currently used to determine local system
time.
*This value has been adjusted for Daylight Saving Time, if
necessary. *

IBM is treating UTC and "offset" as two separate values.. given the
craziness of various geographical areas opting in/out of daylight savings

Weird.

Before you think of changing offset - need to understand how daylight
saving time works

I'm is EST (NC) with an offset = 04.00 so your Central 05.00 seems
right

I am working on a cloud system. The QTIMZON is set to :

Now, I am in MN and the offset I believe should be -06:00 for DST
right
now. I tried changing things and the offset stays at -05:00.

Is there some other setting I'm missing?
