A fio job that just waits?

[Nick Neumann <nick@pcpartpicker.com>]

Is there a clean way to create a fio job that just waits for a fixed
time period? I'm fairly new to fio, and want a delay between two
consecutive jobs. I use "wait_for" to serialize as needed, and
expected "startdelay" to allow me to put the desired delay between the
two. But it looks like the startdelay for a job begins when fio starts
and not when the job referenced in a "wait_for" finishes.

I can play games with a job with a very low bandwidth limit (e.g.
1B/s) and "runtime" and "time_based", but it feels hacky.

Am I thinking about how to get a delay between two jobs wrong? Is
there a better way? I realize I could just run fio multiple times with
command line delays between the runs, but I'd like the results of the
runs to share the same time basis and output/log files.

Thanks,
Nick
