RE: DST PTF(s) for V5R1?

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?

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.
