Re: Time Change

That sounds similar to what I wrote, though I did it in just 1 program. It
ran every Sunday @ 2AM from the job scheduler and simply checked if it was
the right Sunday to spring forward or fall back. If so, it incremented or
decremented the system value for the hour. It also had a check to make
sure that it hadn't already made a change so it wouldn't make a time change
twice.

I may have the source code. I can check tomorrow if there's any interest.
The only updating it would need would be for the new time change dates.

Jerry,

I can't believe I still have them, but ...

Before IBM fixed the system to update the time auto-magicly through system
values and such I had a series of programs that when the first one was
called, put itself on the jobq to run on a future date. When it ran it
scheduled itself for the Sunday of the time change, and changed the time as
appropriate. It then scheduled itself for the next time change cycle. so
..

Spring - Run to get the correct Sunday and schedule the next job.
Spring time change, change the time, then schedule itself to run in the
fall on an appropriate date
Fall - Run to get the correct Sunday and schedule the Fall time change
program
Fall Time change - Change the time, and put schedule the spring job.
...
Rinse, repeat.

I still have the CL source (3 programs I believe) to share on an AS IS
basis, if you would like to look at it and get some ideas from it.

We're on V5R1 here (with no near term hopes of upgrading hardware or OS)

so

the change to DST doesn't happen automagically for us.



In the Fall, I just changed the System vale QTIME early Sunday (we're not
24x7 by any stretch of the imagination) so no user job was impacted. But
Spring may be a different issue.



Anyway, I was reading Bruce, et als, "APIs At Work" tome and came across
the
QWCADJTM api. I was wondering if anyone had used (or are still using)

this

api to adjust the system clock for System i's when on old releases (such

as

ours) that can't/.won't do it? If so, how did it work out for you?



Thanks.
