RE: DST PTF(s) for V5R1? -- MIDRANGE-L

No such system value as QTIMZON in V5R1. There is a QUTCOFFSET which is set to -05:00 for us (Central Time). Is this correct? I ask because the National Institute of Standards shows that it should be -06:00 (http://nist.time.gov/images/US_time_zones.gif).

Message . . . . : Local system time has been adjusted.
Cause . . . . . : Local system time has been adjusted to use a Coordinated
Universal Time offset of -360 minutes due to reason code 2. The reason codes
and their meanings are as follows:
0 - See previous messages.
1 - A Daylight Saving Time transition has occurred.
2 - The time zone currently used by the system value QTIMZON has changed.

Cleanup has started.

Hopefully that "gradual" part is incorrect, and the system - like the rest of the non-personal computer systems in the world - merely "decodes/represents" the time differently rather than actually changing any clock. Nowadays, most systems use the applicable UCT offset to determine what the local time is/was.

Can anyone here confirm the internal process?

V5R3 and enhanced in V5R4. And a search of PTF cover letters shows

older than 5.3.

The "nice" thing about having the system change the time, especially in
the
fall, if I recall correctly, is that the adjustment is gradual, not
instantaneous like I did. A quick change could have an adverse effect
on
things like journals. But ya do what ya gotta do, I guess.

I don't recall which release introduced the link to an SNTP server, but
you
could whip up a program to change the time for you. Stick it in the job
scheduler to run on Sunday mornings, and have it read a 1 record file
containing the actual dates to increase or decrease QHOUR. Plug in the
dates
in January, and you're done for the year.

I'm pretty sure that this is a futile question, but, hey, nothing
ventured.

Yesterday afternoon (Sunday, 6 November) I checked our iSeries machine,
which is running V5R1. The time had not changed. Since no one works
on the
system on weekends, I changed the time manually. Is there a PTF
*still*
available for 5.1 regarding Daylight Savings Time? Our office admin
and I
were trying to remember if anyone had to do anything for DST back in
the
Spring, but I'm old and she's blonde, ergo neither of us could recall
anyone
doing a manual change.

I suspect that I'm stuck with changing the time manually from here on
out.
