Re: Time change and the Advanced Job Scheduler

But is that REALLY how IBM does it?
At one time I thought IBM just brought the time to a crawl during these
fall back times. So as to avoid such an issue. Or maybe I am thinking NTP
corrections?

I ran a test job in base job scheduler on a play ground LPAR, then set the
system time back several minutes, simulating the daylight savings time job.
The job will not run twice.
As Larry previously stated, the "next run time" is set for the job, so job
will only run once.

Word of caution.
If you have a batch job running across the time change, and that batch job
writes time stamps to db records, and the application relies on a date/time
order or the db is keyed by date/time, your application could run into
issues and/or end up with duplicate records.

Long story short, and best practice, avoid the 1 to 3 window.

Subject: Time change and the Advanced Job Scheduler

Hello again all,

I previously asked a question about the upcoming time change and how it
affects automated jobs in the Advanced Job Scheduler. I should have asked
this at the time but I wonder also about the default job scheduler (the
WRKJOBSCDE one). In the case of the WRKJOBSCDE one, we have a job that
runs at 1 am. Is it like the AJS in that it will run once and only once
and set it's scheduled next run date after it runs the first time? All
input appreciated! Thanks!
