I have a requirement to sometimes change the times of scheduled 'at' jobs.
I notice the date/time the job is due to run is not stored in /var/spool/cron/atjobs/xxx and
I can't seem to find where this information is stored/derived. I've run a truss on 'at -l', but that made me
none the wiser.
Is it even possible?
My other choices in are to:
1. Delete and resubmit the job (This can be very messy because of the application generating the jobs)
2. Use a different batch scheduling tool.
I don't want to go down the other paths until I've totally ruled out manipulating the at times directly.
