Hi, note that times reported by sacct may differ from the net times. For example, imagine a test job like this: date sleep 1m date
sacct reports: $ sacct -j 225145 -X -o jobid,start,end JobID Start End ------------ ------------------- ------------------- 225145 2023-02-20T17:31:12 2023-02-20T17:32:30 Whereas: cat *out.225145 Mon Feb 20 17:31:29 CET 2023 Mon Feb 20 17:32:29 CET 2023 Sometimes these extra few seconds matter. So if you're looking for net runtimes, I'd suggest to ask the user to include a date command here and there in the submit script.

I naively assumed that the '-l" in sacct provided "everything" (given how long and unwieldy it is, but I noticed now that it isn't). Sorry for the noise!
