Spawning jobs in a staggered start?

[John]

Is there a way to have parallel spawn jobs on a delayed start with 1 sec delay 
between each one?

In other words, invoke parallel:

job1
sleep 1s && job2
sleep 1s && job3
sleep 1s && job4
...
sleep 1s && jobN

I am calling parallel from a table if that matters:
% parallel -a jobsfile --colsep ',' | ~/bin/myscript
