Has anyone had any "wierd" experiences with their timezone change over the
weekend? On my system, I streamed a job for Sunday at 2 AM. The job
changed the time, paused 60 seconds, then re-streamed the same job for the
following Sunday (in case it's streamed on the wrong week). What happened
is that the job checked the current date, then executed the setclock
command. After pausing for 60 seconds, it re-streamed itself. The 60
second pause should have caused the job to re-stream itself the following
week, but it instead re-streamed itself the same week.
Shouldn't the "Pause 60" command have caused the time to be 2:01 AM, and
the job to re-stream the following week? I thought processes on the system
would not see the gradual time change. Am I having a "DUH" moment??
